Problem 3 A Carnot heat engine receives heat from a reservoir at 1500°F at a rate of 700 Btu/min and rejects the waste heat to the ambient air at 75°F. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at 5°F and transfers it to the same ambient air at 75°F. Determine (a) the maximum rate of heat removal from the refrigerated space, and (b) the total rate of heat rejection to the ambient air. f THE 1500°F 1= 700 Btu/min QHI Rev.
