Question

A reversible heat engine operates between two reservoirs at temperatures of 600 degrees * C and 40 degrees * C . The engine drives a reversible refrigerator which operates between reservoirs at temperatures at 40 degrees * C and -20°C. The heat transfer to the heat engine is 2000 kJ and the net work output of the combined engine refrigerator plant is 360 kJ. 14 i) Evaluate the heat transfer to the refrigerant and the net heat transfer to the reservoir at 40°C. ii) Reconsider (1) given that the efficiency of the heat engine and the COP of the refrigerator are each 40% of their maximum possible values.​
