If you are asked to recommend capacity (in KW) for a backup generator in a building, how would you try to answer this question? What are the main components - list 5 at least of a diesel gen-set
The minimum wattage capacity of the generator depends upon the needs and activities of the residents of the building. But below , we can list some of the basic critical electric circuits and components we need to consider to determine this.
1)Air conditioning- Are they using portable or window unit? Air conditioning is a particularly important thing for people in warmer climates. In general they are 1.5kW-2.5kW. Central AC consumes atleast 5kW , and usually about 8.75kW.
2) Emergency lighting - Typically about 400W. Should be just about enough to serve basic requirements in unforeseen circumstances.
3)Microwave Ovens- Typically 1.6kW to 2.8kW. Exact requirement also depends how on many people actually use microwave for cooking in the building and how many manage with non-electrical sources such as cooking gas only.
4)Well Pump (600W to 900W)- To provide water supply to the residents of the building.
5)Refrigators and Freezers(600W to 2.9kW) - used for storage,cooling,freezing purposes

A synchronous generator is driven by a diesel engine to provide electricity to a remote mining operation. The generator is three-phase, Y-connected, 60 Hz, 900 rpm, 600 V, 3300 kW, 4125 kVA, and it has a synchronous reactance of 0.120 Ω per phase. Ignore all losses, and assume the machine iron is not saturated.(a) The generator is set to deliver its rated active power at unity power factorand rated terminal voltage. Determine:i. The speed of the diesel engine driving the generator;ii. The rotor electrical...
You have been asked to review the design of the aluminum bracket shown on the following page. The bracket will be prototyped by milling and drilling. a. Examine the part model and recommend at least two design changes to improve the manufacturability of the part. Indicate your changes graphically on the figure (or a sketch made yourself), and justify your choices. You may always assume that there is plenty of room for the bolts which will be used to mount...
What Would You Do? You work at a bank and are asked to recommend the amount of cash to put in an ATM each day. You don’t want to put in too much (security) or too little (customer irritation). Here are the daily withdrawals (in 100s of dollars) for 30 days. 72 84 61 76 104 76 86 92 80 88 98 76 97 82 84 67 70 81 82 89 74 73 86 81 85 78 82 80 91...
Use another random decimal fraction generator at Random.org, linked here, to generate a list of ten two-digit random numbers between 10 and 30. Calculate the z-score of the median of the data set. Set 1: 13, 14, 20, 21, 22, 24, 25, 26, 27, 30 What does the z-score of the data set median just above tell you about the shape of the distribution? How do you know this? If you were to take repeated random samples of n =...
Scenario - Imagine you are building a computer from scratch, for yourself, a friend, or as a business investment or sell. Choose ONE type of person you are building this PC for (i.e., Gamer, Standard Home User, Home Business Owner, etc...).Write at least one paragraph (250-300 words) about the type of person you are building this computer for and what their needs are. Keep in mind the components you will need will determined by the needs of your customer (i.e....
Please answer question 4 with the graph and info given below the
problem statement. Thank you : )
4. Assume that the generator field current is adjusted to supply 480 V under rated condi- tions. What is the static stability limit of this generator? (Note: You may ignore RA to make this calculation easier.) How close is the full-load condition of this generator to the static stability limit? Problems 2 to 4 refer to a four-pole, Y-connected synchronous generator rated...
In a survey of 1147 small-business owners, the following question was posed: Would you recommend working with a significant other? Sixty-one percent of those polled answered in the affirmative, whereas 39% answered in the negative. Assuming that this result reflects the view of all small-business owners, what is the probability that at least 8 out of 10 small-business owners selected at random will opine that it would be unwise to work with the significant other? (Round your answer to four...
A consulting company has asked you to choose a new hub for a regional airline that serves the major airlines and helps the major airlines go to the smaller cities. What are the top two new hub locations that you would recommend? Your job is to be a consultant on this decision. The committee has asked you to analyze the decision using the decision analysis process below. 1: Identify the decision situation and understand objectives 2: Identify alternatives 3: Decompose...
