Question: A reversible heat engine operates between (875 mathrm{~K}) and (310 mathrm{~K}) and drives a reversible refrigerator operating between (310 mathrm{~K}) and (255 mathrm{~K}). The engine

A reversible heat engine operates between $875 \mathrm{~K}$ and $310 \mathrm{~K}$ and drives a reversible refrigerator operating between $310 \mathrm{~K}$ and $255 \mathrm{~K}$. The engine receives $2000 \mathrm{~kJ}$ of heat and net work output from the arrangement equals $350 \mathrm{~kJ}$. Make calculations for cooling effect.
