Here's my problem:
A heat pump cycle whose coefficient of performance is 2.5 delivers energy by heat transfer to a dwelling at a rate of 20 kW.
a) Determine the net power required to operate the heat pump, in kW.
b) Evaluating electricity at 8 cents per kWh, determine the cost of electricity in a month when the heat pump operates for 200 hours.
I know that the coefficient of performance = Qout/Wcycle = Qout/(Qout-Qin).
But what is meant by net power? And more importantly, how do I calculate it?
Thanks for help in advance,
