Carnot heat engine obtains 3000 kJ heat from a high-temperature reservoir at 850 deg C. It rejects the waste heat to a low-temperature reservoir at 75 deg C. The work produced by the Carnot heat engine is used to power up a reversible refrigerator that removes heat at a refrigerated space maintained at -10 deg C. The heat removed is discarded in the same low-temperature reservoir as that of the Carnot heat engine. The work net output of the combined heat engine and refrigerator plant is 400 kl. Determine the total heat rejection if the actual efficiency of the heat engine and COP of the refrigerator is 45% of the maximum possible values
