Acarnot heat engine operates between 1000 k and 300 k (atmospheric temperature) and uses the net work output to drive a refrigerator, also working on a carnot (ideal reversible refrigeration) cycle. the refrigerator maintains the cold space at 240 k. if the heat input to the carnot heat engine is 100 kw, determine the cooling capacity (heat removed from the cold space) of the refrigerator in kw

Acarnot heat engine receives heat at 750°c and rejects the waste heat to the environment at 30°c. the entire work output of the heat engine is used to drive a carnot refrigerator that removes heat from the cooled space at -25°c at a rate of 300 kj/min and rejects it to the same environment at 30°c. determine: i. the thermal efficiency of the heat engine ii. the coefficient of performance of the refrigerator iii. the work input to the refrigerator iv. the minimum rate of heat supply to the heat engine, and v. the total rate of heat rejection.
