Problem 2

Example 6.14 A reversible heat engine operates

between two reservoirs at 600°C and 40°C. The engine

drives a reversible refrigerator which operates between

the same 40°C reservoir and a reservoir at -18°C. The

heat transfer to the heat engine is 2100 kJ and there is

a net work output of 370 kJ from the combined plant.

Evaluate the heat transfer to the refrigerator and the net

heat transfer to the 40°C reservoir.
