Load Calculation Voltage Drop And Size Cable

Load Calculation Voltage Drop And Size Cable Before wiring installation process is carried out, it must follow the rules of Malaysia 1994. which requires all wiring, additional wiring or rewiring to carried out by Electrical Contractor or Electrical Wiring Unit require approval writing from the licensee or supply authority. Wireman or Contractor need to plan and indentify the work want to carried out, so that work can be more clean, tidy and safe to uses. the wireman or contractor should: Make a site visit Follow the guideline regulation from JKR identifies the user load requirement calculate the maximum demand and total connected load determine the equipment submit plants, drawings and specifications 2.0 Regulation and Nominal Voltage in Malaysia 2.1 The Regulation Electricity supplied to domestic consumers must be follow standard specification, which are: MS MSIEC International Electro technical Commission, IEC British Standard , BS the current British standard has integrated with the European standard, BSEN European Standard, EN Electricity supplied also need to refer akta bekalan elektrik years 1990. This act is to provide for the investing of property and liabilities of the lembaga letrik negara in a each company, to make financial arrangement for that company, to provide for matters relating to employee and for other matters connected therewith Guidance notes for wiring regulation can refer IEE wiring regulation by Brian reference for all contractors, technicians and other professionals working in a non- supervisory capacity, as well as newcomers to the industry, all of whom are involved in inspecting and testing electrical installations, and need to ensure their work complies with the latest version of the Wiring Regulations. The installation on equipment and so on need to follow regulation from JKR such as : L-S1 : Specification for low voltage internal electrical installation system L-S2 : Specification for low voltage automatic power factor correction L-S3 : Specification for low voltage underground cable L-S4 : Specification for low voltage overhead line distribution L-S5 : Specification for three phase generator set L-S6 : Specification for acoustic treatment for generator room L-S7 : Specification for single phase diesel generator set L-S8 : Specification for lightning protection system( using stranded G.I wires) L-S9 : Specification for lightning protection system for structures 2.2 Nominal Voltage in Malaysia The official mains power voltage is AC 230 V with the tolerance of +10%,- 6%. However, the supplied voltage remains at 240 V, as the supplied voltage is within the allowed tolerance. Areas that rely on private power companies, like some parts of Penang and Kedah, receive a true 230 V supply. Remote villages which rely on off-grid localized diesel generators (i.e. small villages and/or isolated holiday resorts on islands too far away from the mainland to have viable underwater cabling) may receive unstable power with higher voltages, with some areas recorded to be as high as 260 V Before this, the rated voltage in Malaysia is 240/415V with range +5% to -10%, and effective in January 2008 the rated change to 230/415V with range +10% to -6% 3.0 Load Calculation Each design want to be made need go through the process of load calculation, where the process is calculated from distribution board(DB), sub-switch board(SSB) and main switch board(MSB) A distribution board is a panel or enclosure that houses the fuses, circuit breakers, and ground leakage protection units used to distribute electrical power to numerous individual circuits or consumer points. The board typically has a single incoming power source and includes a main circuit breaker and a residual current or earth leakage protection device. A distribution board may be used to distribute either single or three phase supplies depending on the installation specifics. Although distribution board equipment, layouts, and legislative requirements differ from country to country, the basic principles of distributing a single supply to various individual points while ensuring safety and control for each remains the same. sub-switchboard function is same as distribution board, but MSB is MSB is an assembly of distribution panels, each of which contains switches and breakers that allow electricity to be redirected to appropriate loads. The role of MSB is to divide the main curre nt provided to the switchboard into smaller loads for further distribution and to provide switching, over-current protection and metering for these various loads. 3.1 Type of load Electrical load types fall into four categories: resistive, capacitive, inductive or a combination of these. Few loads are purely resistive, capacitive or inductive. The imperfect nature of how electrical and electronic devices are built causes inductance, capacitance and resistance to be an inherent part of many devices. 3.1.1 Resistive Loads A resistor is a device that resists the flow of electricity. In doing so, some of the electrical energy is dissipated as heat. Two common resistive loads are incandescent light bulbs and electric heaters. Resistance (R) is measured in ohms. An incandescent light bulb produces light by passing an electric current through a filament in a vacuum. The resistance of the filament causes it to heat up and the electrical energy is converted to light energy. Electric heaters work in the same way except they produce little, if any, light. The electrical current and the voltage in a resistive load are said to be in phase with each other. As voltage rises or falls, the current also rises and falls with it. 3.1.2 Capacitive Loads A capacitor stores electrical energy. Two conductive surfaces are separated by a non-conductive insulator. When an electrical current is applied to a capacitor, electrons from the current gather on the plate attached to the terminal to which the electric current is applied. When the current is removed, the electrons will to flow back through the circuit to reach the other terminal of the capacitor. Capacitors are used in electric motors, radio circuits, power supplies and many other circuits. The capability of a capacitor to store electrical energy is called capacitance (C). The main unit of measure is the farad, but most capacitors are measured in microfarads. The current leads the voltage of a capacitor. The voltage across the terminals starts out at zero volts while the current is at its maximum. As the charge builds on the capacitors plate, the voltage rises and the current falls. As a capacitor discharges, the current rises as the voltage falls. 3.1.3 Inductive Loads An inductor may be any conductive material. When a changing current passes through an inductor, it induces a magnetic field around itself. Turning the inductor into a coil increases the magnetic field. A similar principal occurs when a conductor is placed within a changing magnetic field. The magnetic field induces an electrical current within the conductor. Inductance (L) is measured in henries. The changing voltage and current in an inductor are out of phase. As current rises to a maximum, the voltage falls. 3.1.4 Combination Loads All conductors have some resistance under normal conditions and also exhibit inductive and capacitive influences, but these small influences are generally dismissed for practical purposes. Other loads make use of various combinations of inductors, capacitors and resistors to perform specific functions. The tuning circuit of a radio uses variable inductors or capacitors in combination with a resistor to filter out a range of frequencies while allowing just one narrow band to pass through to the rest of the circuit. A cathode ray tube in a monitor or television makes use of inductors, resistors and the inherent capacitance of the tube to control and display a picture on the phosphor coatings of the tube. Single phase motors often use capacitors to aid the motor during starting and running. The start capacitor provides an additional phase of voltage to the motor since it shifts the current and voltage out of phase with each other. 3.2 Total Connected Load(TCL) and Maximum Demand(MD) One of the most calculation basic electrical calculation is to calculate the total connected load(TCL) and maximum demand(MD) The TCL is the mechanical and electrical load that will be connected for that particular area, where all of the electrical loads in an installation be maximized and simultaneously, The MD is the total kW that actually contributes the total power used in one time after applying the diversity factor based on the Total Connected Load calculated. It less than or equal to the connected load (TCL). Value of maximum demand of a building and ratio of diversity factor must be determined so as not overdesigned or under designed. By using MD also, many cost can be reduced as cable size, the size of the breaker, busbar size etc By calculating the TCL, it can know the total load connected for a particular area and also can determine the sizing of cables. But, the most important thing is by having the TCL, it can determine the MD. This MD will be declared to the utility provider for the purpose of meter deposit and utility bill 3.2.1 Diversity Factor (DF) Diversity factor is different or ratio between MD and TCL. the equation can relate MD, TCL to DF is : MD = TCL x DF Should be reminded, to determined DF normally it can not be precisely determined. DF value is only an approximate value only based on the guidance or previous data. The diversity factor is almost always greater than 1 since all components would have to be on at simultaneously at full load for it to be one. 3.2.2 Increase Burden After MD known then it should be added 20% at DB and 30% in SSB or MSB to determine the size of the incoming breaker. This is because taking into account the increase in the load in the future. it is known as increase burden. The specification percent of increase burden: Distribution Board School: MD + 20% Office : TCL Hospital : TCL + 20% Sub Switchboard and Main Switchboard MD + 30% 3.3 Circuit Breaker To provided adequate over current protection, each circuit should be equipped with a circuit breaker for automatic interruption of supply in the event of overload current and fault current. the circuit breaker installed in a circuit should break any fault current flowing in the circuit breaker before such current causes danger due to thermal or mechanical effect produced in the circuit or the associated connection. the characteristics of the breaker shall satisfy the condition that the breaking capacity should be greater than or equal to the prospective short circuit current or earth fault current at the point at which the breaker installed The rated current of a circuit breaker is the current that it can carry continuously, generally for a duration of more than eight hours. The rated current must not cause a temperature is between -5C to 40C. Different temperature rise limits are specified for different parts of a circuit breaker. A circuit breaker will not operate (Trip) if the current passing through it is 105% to 113% of its rated current. It will take one or two hours to trip if the current passing through it is 130% to 145% of the rated current. 3.4 Type of Circuit Breaker need to be determined 3.4.1 Miniature Circuit Breaker(MCB) MCB are used extensively for the protection of final circuit in domestic and commercial installations. they offer these circuit protection, particularly when overload or short circuit conditions are being considered than the fuse alternatives. MCBs are available for both single phase and three phase circuit. In a single phase circuit, a single MCB may be used in the live conductor or a two-pole MCB connected in the live and natural conductor. three or four pole MCBs are used for protection in three phase supplies. If a fault current flow through even one pole of an MCB, all the three poles will be operated. The main standard for MCBs in BS 3871. This standard covers MCB ratings up to 100A, breaking capacities up to 9 kA and voltage ratings up to 415V The preferred value of the rated current are : 6, 8, 10, 13, 16, 20, 25, 32, 40, 50, 63, 80, 100, and 125A Instead of specifying the breaking capacity, the standard specifies the value of the short circuit capacity. the short circuit capacity refers to the prospective current expressed by its r.m.s value which the MCB is designed to make (closed), to carry for its operating time and to break under the specified conditions. the standard value of rated short circuit are 1.5, 3, 4.5, 6 and 10kA. for values above 10kA up to and including 25kA, the preferred value 20kA 3.4.2 Moulded Case Circuit Breaker(MCCB) Moulded case circuit breaker(MCCB) are required for installation which have higher fault level or higher current ratings exceeding 125A. MCCBs have several advantages over ordinary switches and fuses in the control and protection of circuit and apparatus. they have a repeatable non-destructive performance and are safe in operation under fault conditions. it has built-in mechanism to simultaneously open all three phases for a single phase fault. These circuit breaker are mainly used to protect main feeder cables, for incoming supply to sub circuit/distribution boards and for large motor circuit. for installation, MCCBs are suitable as free standing units, or for building into compact cubic-type switchboards. Auxiliary items such as shunt trio elements, status switches, interlocks and motor-operated mechanism for remote operating can all be integrated into the MCCB. The main industrial standard for MCCBs are BS EN 60947-1 and BS EN 60947-2. these two standard define the characteristics, conditions for operation, methods for testing and the requirements for circuit breaker with rated voltages up to and including 1000V a.c or 1500 d.c. As there are no other standard values specified in BS EN 60947, the followings are some typical technical data for reference : Current rating : 10, 16, 20, 32, 40, 50, 63, : 80, 100, 200, 300, 400, : 630, 800, 1250A Rated voltage : 380, 400, 415V Rated breaking capacity : 10, 20, 25, 35, 65, : 85kA(r.m.s) Rated making capacity : 17, 44, 53, 63, 84, : 143kA(peak) One minutes power frequency withstand voltage : 2.5kV 3.4.3 Residual Current-operated Circuit Breaker(RCCB) The Residual Current-operated Circuit Breaker(RCCB) are primarily designed to protect against indirect contact electric shock. The term indirect contact refers to the contact of the supply voltage indirectly through the touching of the exposed-conductive-part such as the metalic enclosures of electrical appliances, the metallic conduit, trunking or cable tray. These exposed-conductive-part are insulated from the live conductor and are connected to the earthing terminal and thus, should be at the earth potential. However, during an earth faults, as there is an earth fault current flowing from the love conductor through the exposed-conductive-part to the earth, the exposed metalwork may be at high potential relative to earth. touching the exposed- conductive-parts at this instance may cause an electric shock if its potential to earth exceeds 50V. Furthermore, id it is a high impedance earth fault, the magnitude of the earth fault current may not activate the overcurrent protective device. Thus, a current will continue to flow to earth, possibly generating heat and causing fire. RCCB is designed to detect such a residual current (ie. earth leakage current), to compare it to reference value and to open the protected circuit when the residual current exceeds this reference value. RCCBs are not designed to have a high breaking capacity and in fact, they have only a limited breaking capacity. They are therefore, not a replacement for other overcurrent protective devices which are designed to interrupt high fault current. There are four standard for RCCBs namely, BS4293, IEC 755, IEC 1008- 1 and Singapore standard SS 97. Based on IEC 1008, RCCBs are specified as follows: Preferred rated voltage : single phase, phase to neutral : 230V :three phase, three wire :400V : three phase, 4 wire : 400V Preferred rated current, IN :10, 13, 16, 20, 25, 32, 40, 63, 80, 100, 125A Rated residual operating current,IË„N : 0.006, 0.01, 0.03, 0.1, 0.3, 0.5A Standard value of residual non operating current : 0.5 IË„N minimum value of the rated making and breaking capacity :10 IN or 500A whichever is greater Rated condition short circuit current : 3, 4.5, 6, 10, 20kA Maximum break time : 0.3s for residual current equal to 0.5 IË„N : 0.15s for residual current equal to 20.5 IË„N : 0.04s for residual current equal to 50.5 IË„N 0.004s for residual current to 500A 4.0 Voltage Drop Voltage drop difference in voltage from one point in a current path to any other point in the same current path. Voltage drop is the result that happens to a voltage value when it meets with resistance in any current path while current is flowing, it only happens when flowing current meets resistance in a current path, the higher the value of current flowing, the higher the voltage drop across any conductor, connection, or contact in the current path. Based on Ohms law; it takes one volt to push one amp through one ohm of resistance. The location of a voltage drop in a parallel circuit determines the affect it will have on the loads that are in parallel. When a voltage drop occurs before, or ahead of the last parallel splice in a parallel circuit, it will provide less than source voltage to all loads in parallel beyond the last parallel splice. When a voltage drop occurs after the last parallel splice in a parallel circuit, the same value of voltage drop has an identical affect on the load in the affected branch whether it appears on the voltage feed side, or on the ground side of the branch load. When current flows through the cable, the voltage drop will result. This is based on a formula : V = I x R ; I = current flows through the cable R = Resistance of the cable Based on requirement of IEE wiring regulation 525-01-01. The voltage drop between the origin of the installation (usually the supply terminals) and terminals of the fixed current using equipment does not exceed 4% of the nominal voltage of the supply. The voltage drop for building must make sure it not more than 4% depend to nominal voltage, where : 4% of 1ÃŽÂ ¦ = 4% of 240 V = 9.6 Volt 4% of 3 ÃŽÂ ¦ = 4% of 415 V = 16.6 Volt The voltage drop for outside building, must not exceed 20V from nominal voltage 4.1 The Voltage Drop is Closely Related with Size of Cable Most circuits in a house do not have enough current or length to produce a high voltage drop. In the case of very long circuits, for example, connecting a home to a separate building on the same property, it may be necessary to increase the size of conductors over the minimum requirement for the circuit current rating. Heavily-loaded circuits may also require a cable size increase to meet voltage drop requirements in wiring regulations. Voltage drop and size cable can related with equation : VD Total of voltage drop Vd Voltage drop on cable mV/A/m In Rated current of breaker (A) L Length of Cable (meter) 5.0 Cable In electrical engineering cables are used to carry electric currents. Cables are the mean by which electrical energy is distributed from its source to its point of use. Copper wires in a cable may be bare, or they may be plated with a thin layer of another metal, most often tin but sometimes gold, silver or some other material. Tin, gold, and silver are much less prone to oxidation than copper, which may lengthen wire life, and makes soldering easier. http://www.electronicsteacher.com/direct-current/dc-metering-circuits/00376.png 5.1 Insulation The insulation surrounds each conductor to prevent direct contact between individual conductors and earth. Type of insulation will depends on the voltage, the operating temperature of the conductor and the mechanical and environmental condition affecting the cable during both installation and operation. Type of insulation material: Polyvinyl chloride (PVC) Rubber Cross-linked polyethylene (XLPE) Powdered mineral Oil impregnated paper tapes 5.2 Type of conductor PVC, PVC/PVC XLPE, XLPE/PVC (>25 mm2) PVC/SWA/PVC XLPE/SWA/PVC (>25 mm2) Fire Rated Cable MIMS (Mineral Insulated Mineral Sheathed Copper Conductor) MICC (Mineral Insulated Copper Clad Copper Conductor) 5.3 Installation method GI Conduit PVC Galvanised/H.D.G. Trunking PVC Hot Dipped Galvanised Perforated Cable Tray PVC/PVC, XLPE/PVC, PVC/SWA/PVC, XLPE/SWA/PVC Hot Dipped Galvanised Cable Ladder PVC/PVC, XLPE/PVC, PVC/SWA/PVC, XLPE/SWA/PVC 5.4 Cable type and selection The current carrying capacity of a cable must be sufficient to cater for the maximum sustained current which will normally flow through it. The insulation must be adequate to deal with the voltage of the system and must not be damaged by the heat produced by the current flow, high ambient temperature or by heat transferred. Cable selection therefore is primarily related to the size of the cable which will carry the required current without the temperature of the surrounding insulation rising above a critical level which will result in the breakdown of the insulation. 5.5 Current rating of cable The current rating of cable is determined by a number of factors: Ambient temperature Maximum allowable conductor temperature Conductor material insulation material Installation method 5.6 Determine the Size cable The proper sizing of an electrical (load bearing) cable is important to ensure that the cable can: Operate continuously under full load without being damaged Withstand the worst short circuits currents flowing through the cable Provide the load with a suitable voltage (and avoid excessive voltage drops) (optional) Ensure operation of protective devices during an earth fault Selected the size cable can base on : In à ¢Ã¢â‚¬ °Ã‚ ¥ Ib Iz à ¢Ã¢â‚¬ °Ã‚ ¥ In Iz à ¢Ã¢â‚¬ °Ã‚ ¥ In à ¢Ã¢â‚¬ °Ã‚ ¥ Ib * In rated current Iz rated current of cable Ib design current

How to Be Healthy Essay

Specific Purpose: â€Å"To inform my audience about how to eat healthy.† Central Idea: In this speech, I’ll be explaining why it is important to eat healthy, and give tips on what to do to initiate healthier eating habits. Introduction: Attention Getter: How many of you want to be healthy? Credibility Material: My mom is a dietitian; which is a person who specializes in the study of food and nutrition in relation to health, and she’s always stressing to my brother and I to eat up vegetables and to eat fruit everyday. Relevance to the Audience: Almost everybody knows that it’s important to eat healthy. However, not everybody can explain exactly why. Healthy eating is essential for a number of reasons, and not all of them are as obvious as â€Å"getting your vitamins.† Preview of Main points: Why pay attention to what you eat? Is healthy eating the same as going on a diet? How to eat to be healthy? Link: First off†¦ I. Why pay attention to what you eat? A. Healthy eating is one of the best things you can do to prevent and control many health problems, such as Obesity, Heart Disease, High Blood Pressure, Type 2 Diabetes, & Some types of cancer. 1) According to the Centers for Disease Control & Prevention, about one-third of U.S. adults (33.8%) are obese and approximately 17% (or 12.5 million) of children and adolescents aged 2—19 years are obese. Even for people at a healthy weight, a poor diet is associated with major health risks that can cause illness and even death. B. Healthy foods are full of nutrients that contribute to the health of your skin, hair and nails. These nutrients not only make you look better, but also keep your skin healthier. C. You’ll benefit your brain. The Alzheimer’s Association says a brain-healthy diet is one that reduces the risk of heart disease and diabetes, encourages good blood flow to the brain, and is low in fat and cholesterol. Like the heart, the brain needs the right balance of nutrients, including protein and sugar, to function well. Link: Next†¦ II. Is healthy eating the same as going on a diet? A. Healthy eating is not a diet. It means making changes you can live with and enjoy for the rest of your life. Diets are temporary. Because you give up so much when you diet, you may be hungry and think about food all the time. And after you stop dieting, you also may overeat to make up for what you missed. B. C. Eating a healthy, balanced variety of foods is far more satisfying. And if you match that with more physical activity, you are more likely to get to a healthy weight-and stay there-than if you diet. Link: Now that I’ve told you the differences between healthy eating and diets†¦ III. How to eat healthy? A. It’s easier than you think to start eating healthy! The U.S. Department of Agriculture has set guidelines for a healthy diet. The USDA’s â€Å"MyPyramid† divides food into five groups and explains how much of each food group you need, as well as the benefits of each food group. Following the USDA’s recommended dietary guidelines can help reduce the risk of some diseases, including heart disease. B. Small changes can make a big difference to your health. Try incorporating at least six of the eight goals below provided by the President’s Council on Fitness, Sports & Nutrition into your diet. Commit to incorporating one new healthy eating goal each week over the next six weeks. 1) Make half your plate fruits and vegetables. 2) Make half the grains you eat whole grains. 3) Switch to fat-free or low-fat (1%) milk. 4) Choose a variety of lean protein foods. 5) Compare sodium in foods. 6) Drink water instead of sugary drinks. 7) Eat some seafood. 8) Cut back on solid fats Conclusion: In conclusion, healthy eating is not about strict nutrition philosophies, staying unrealistically thin, or depriving yourself of the foods you love. Rather, it’s about feeling great, having more energy, stabilizing your mood, and keeping yourself as healthy as possible.

Women s Roles And Gender Stereotypes Essay - 1154 Words

Women’s Roles The Simpsons is a TV show that airs on the Fox network. During the fifth season, in an episode called Lisa vs. Malibu Stacy, Lisa challenges the makers of the Malibu Stacy doll to create a less sexist doll. The original creator of Malibu Stacy teams up with Lisa to create Lisa Lionheart to create a positive influence for young girls. This episode raised a lot of questions regarding gender roles and stereotypes. Gender stereotypes are prominent in today’s life style. Per gender stereotypes, girls like princesses and boys like cars. These gender roles, however, do not just apply to children. These roles are still very prominent in â€Å"grown up† society. The pay gap between men and women Gender roles are a big part of humankind society. There is insurmountable evidence that points to the idea that gender stereotypes is largely accomplished through social factors. Scholars in both sociological and psychological fields believe that gender is constructed through the modeling of appropriate behaviors and the use of systematic rewards and punishments. Evidence also shows that many aspects of gender are not innate, as evidenced by children who do not exhibit a gender specific preference in friends, clothing or toys when placed in gender neutral settings. Only after negative reactions from parents, teachers, or friends do many children begin to take on the gender roles society comes to see as appropriate for them.

Solar Energy Why do we build passive solar homes? Most people familiar with the subject of alternative and renewable energies would reply with a variation of many answers to this question. â€Å"To act locally in an ever expanding global market.† â€Å"The solar panels or photovoltaics will pay for themselves in a given amount of time depending on the system implemented.† â€Å"I would build a passive solar house to take myself entirely off the grid.† These answers seem to be common when it comes to the world of alternative energies. Although the majority may reply to this question with similar answers there has to be a flip side or different view on any topic including renewable energy. â€Å"Green building,† or building with natural supplies†¦show more content†¦No, we obviously cannot reverse the chain of events that has brought us to this point but we can individually do our part to stop the on going process. Technology has brought us to where we are today as humans. For better or worse this is where we are and we are stuck with it. We need to use technology to our advantage in our everyday lives. This is where passive solar technology comes into play. It is, in a sense, a gathering of the new and old for a better world. Our ancient ancestors may have caused war and been unjust but they did not place the future of the world on the brink of extinction. As present citizens of earth our living habits dictate the way we use earth’s resources. We need to curb our ways and live â€Å"closer† or more in-tune with our mother earth. Greeks and Romans used passive designs in their architecture for such purposes as community baths and meeting halls as well as orientating their living spaces also. This technology is nothing new, so we have the ability to do this type of building on a large scale. The design concept is a huge part of this process for present day building, such as it was when the Greeks and Romans designed their architecture. One must figure out the best way of designing a living space for the intended environment or climate. The passive heating and cooling of the living space entirely depends upon this.

The Representation Of Democratic Democracy - 993 Words

Elections in America The role of elections in America is to serve the representative democracy. In a representative democracy one person represents the voting patterns, and acknowledgements of other people. American citizens, who cast votes to improve delegation problems, solve coordination problems, and pick an agent over another serve representative democracy in American elections. American elections serve this goal by creating campaigns, advertising on television, and by free information being delivered to its citizens. Campaigns are not so cheap, as millions of dollars are spent in just campaigning for a candidate during Presidential elections. â€Å"Each campaign emphasizes selected facts and cues aimed at getting at least a plurality of voters to the polls† (499, 6th edition). The goal of campaigns is to communicate the meaning of the election to the American citizens. The various facts and cues delivered to American citizens in different campaigns helps the citizens choose which presidential candidate would be their best pick. â€Å"Candidates and campaigns are also encouraged by elections to help solve the immense amount of coordination problem, which are confronted by millions of American citizen voters doing their best to act mutually to control or change their agents† (521, 6th edition).

Marketing Strategy and Plan Health Conscious People

Question: Discuss about theMarketing Strategy and Planfor Health Conscious People. Answer: Marketing Analysis: Dear Friends, Refer to the SWOT analysis made by Marketing Strategy Team about the exploration of new market in Australia emphasis is to be given on the suburb areas with affluent, health conscious people. To keep in mind competitive factor, the expansion proposal is as follows:- Identification of New markets: Ringwood- Eastern Suburb of Melbourne Fitzroy- Inner city suburb of Melbourne Petersham- inner west suburb of Sydney St Lucia- Inner city suburb of Brisbane Expected contribution of these new markets for business growth: All these new locations chosen for business growth have the potential to provide good business opportunity related to the service extended by Tri Fitness. The expected business growth from these sites can be generated as follows:- Ringwood- can generate business of $ 40,000 per month with the partnership of health clubs and swimming pools. Fitzroy- can generate business of $ 20,000 per month by making strategic alliance with leisure clubs Petersham- can generate business of $ 30,000 per month by making partnership with the existing swimming pool Lucia- can generate the business of $ 25,000 per month by providing the service to the people through community health organizations Steps to identify potential market opportunities of these markets: To enter- Entering in these markets will be easier as the inhabitants of those places need this service in economic way to pamper their health awareness. To shape- initial arrangements are to be made with the strategic partners like swimming pools, leisure clubs and health clubs and the community health organizations of the local authorities(Berry, 2005). To influence- A good advertisement with the brand name and logo of Tri Fitness in the local newspaper will do the needful to influence the target audience which can be derived through a brisk market research(Palin, 2015). Please revert with your feedback, Regards, Task B: Marketing Opportunities: Dear Friends, Refer to my Email and subsequent reply from your end regarding the marketing ideas innovated at your end, given below further elaborate presentation for your perusal. Refer to my earlier mail I have given the prospect of business growth in the new markets which had been reviewed by you and the reply had encouraged me to give more specific idea related to business growth of the new places, as specified by me. The expected business from Ringwood can have the potential of generating business worth $ 50,000 per month considering the target audience and their awareness related to health consciousness. The competition will not be so hard as I have expected as the supply and demand line of health fitness business is not catered there with abundance. Fitzroy has the lesser potential as I have predicted but the feedback from your team can not allow me to be so optimistic, hence the projected business from this area can be considered as $ 10,000. Petersham Is with the population who has the regular habit of going to the health clubs or passing time in the swimming pools. The report from your team makes me optimistic of getting the business of $ 40,000 per month with additional awareness program to be made in the community. St Lucia will feature with the expected business range of $ 20,000 initially as the population there with health consciousness is already with the practice of going to the healt h clubs and the stiff competition will yield with the turnover of $ 20,000, as anticipated(Entrepreneur, 2003). To endorse the innovative ideas to exploit the marketing opportunities, I can highlight on the issues of: Identification of target audience followed by direct interaction Provide the list of facilities to be extended to them for membership they enter Direct FM advertisement in the morning from 7 to 8 Am to catch the target audience Hope the same will be good for exploration of new market in the specified areas. Feel free to revert for any other suggestions. Wish all the best. Regards, References: Berry, T. (2005, June 13). Conducting a Market Analysis for Your Business Plan.
