A carnet heat engine receives heat from a hot reservoir of a temperature 327°c and it rejects the heat to an enviroment with an atmospheric temperature of 27°c . The entire work output of the heat engine is used to run a refrigerator which transfers heat from freezing compartment with a temperature of -23°c and rehects the heat to the same enviroment . Cooling rate required by the refrigirator is 4.5 kW. A) if the rate of heat transfer from hot reservoir to the heat engine is 0.90 kW . Predict the minimum additional power required to run the refrigerator . B) predict a minimum rate of heat transfer from hot reservoir to the heat engine required in order to run the refrigerator without any additional power
