An air conditioner operating at steady state maintains a dwelling at 70oF on a day when the outside temperature is 90oF. If the
rate of heat transfer into the dwelling through the walls and roof is 30,000 Btu/h, might a net power input to the air conditioner compressor of 3 hp be sufficient? If yes, determine the coefficient of performance. If no, determine the minimum theoretical power input, in hp.
