Acarnot heat engine receives heat from a reservoir at 900°c at a rate of 800 kj/min and rejects the waste heat to the ambient air at 27°c. the entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at -5°c and transfers it to the same ambient air at 27°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.
