A heat pump cycle delivers energy by heat transfer to a dwelling at a rate of 40,000 Btu/h. The coefficient of performance of the cycle is 3.8. (a) Determine the power input to the cycle, in hp. (b) Evaluating electricity at $0.085 per kWh, determine the cost of electricity during the heating season when the heat pump operates for 2000 hours. W cycle = i Cost = $i hp
