Question: A Carnot heat engine receives heat from a reservoir at 1700F at a rate of 700 Btu/min and rejects the waste heat to the ambient

A Carnot heat engine receives heat from a reservoir at 1700°F at a rate of 700 Btu/min and rejects the waste heat to the ambient air at 80°F. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at 20°F and transfers it to the same ambient air at 80°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.
