A reversible heat engine operates between 397 degrees C and 7 degrees C and rejects 20 kJ/min to the environment. The total net work output of the engine is used to drive a reversible heat pump which is supplied with heat from the environment at 7 degrees C and rejects heat to a home at 40 degrees C.
A) Determine the net work delivered by the engine into W.
B) Determine the heat supplied to the heat pump, in kJ/min.
C) Determine the coefficient of performance of the heat pump.
