A reversible heat engine operates between two reservoirs at temperatures of 600C and 40 °C. The engine drives a reversible refrigerator which operates between reservoirs at temperatures of40 °C and-20°C. The heat transfer to the heat engine is 2000 kJ and the net-work output ofthe combined engine refrigerator plant is 360 kJ. What is the heat transfer to the refrigerant and the net heat transter to the reservoir at 40 °C? (a)The heat transfer to the refrigerant is 3891,7kJ (b) The heat transfer to the tefrigerant is 4899.0kI (c) The net heat transfer to the reservoir at 40°Cis 5531.7 kJ. (d) The net heat transfer to the reservoir at 40 °C is 6539.3 kJ.
