A house is cooled by the removal of 68 000 Btu/h using a reversed Carnot cycle. Assume that the house is kept at 72°F and that the outside temperature is 90°F. If the motor used is rated at 6.5 hp and electricity costs 14 cents/kW·h, determine the cost per day to operate this cycle. Repeat this problem for a 4-hp motor, and compare your results. Note that this is an ideal cycle and that all processes are ideal.
