A Carnot heat engine receives heat from a reservoir at 900$^\circ{}$C at a rate of 800 kJ/min and rejects the waste heat to the ambient air at 27$^\circ{}$C. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at -5$^\circ{}$C and transfers it to the same ambient air at 27$^\circ{}$C. Determine (a) the maximum rate of heat removal from the refrigerated space and (b) the total rate of heat rejection to the ambient air. Answers: (a) 4982 kJ/min, (b) 5782 kJ/min

Your Design Should Work According To These Specifications: 1. ... Your first task is to design a reversible and adiabatic air compressor powered by a steam turbine. Your design ... The compressor should receive 20m^3/s of air delivered at 101 kPa and 25C. 2. The compressed air should exit the compressor at 680 kPa. 3.
