For the business whose monthly electrical energy use is described in Problem 1-5, estimate the average rate of energy use in kw, assuming it uses energy only from 7:00 A.M. to 6:00 P.M ., Monday through Friday in a 31-day month. Assume that the month starts on a Monday to give 22 working days that month. Calculate the ratio of the peak demand set during that month to the average rate of energy use, What reasons would likely cause the ratio to be high'?
