Question
Quiz-ch5 A Carnot heat engine receives heat from a reservoir at 1200°C at a rate of 800 kJ/min and rejects the waste heat to the ambient air at 32°C. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at -7°C and transfers it to the same ambient air at 32°C. Determine (a) the maximum thermal efficiency of the heat engine, (b) the maximum power output of the heat engine (kJ/min), (c) the maximum COP of the refrigerator, (d) the maximum rate of heat removal from the refrigerated space (kJ/min). 1200 'C -7 °C 1000 KJ/min (HE) 32 °C
