An exercise room has eight weight-lifting machines that have nomotors and four treadmills each equipped with a 2.5-hp(shaftoutput) motor. The motors operate at an average load factorof 0.7, at which their efficiency is 0.77. During peakevening hours, all 12 pieces of exercising equipment are usedcontinuously, and there are also two people doing light exerciseswhile waiting in line for one piece of the equipment. Assuming the average rate of heat dissipation from people in anexercise room is 525W, determine the rate of heat gain of the exercise room from people and the equipment at peak load conditions. Note: 1hp = 745.7W.
