Question:
The efficiency of a machine is in general defined as the ratio between useful (released) energy and the input energy. Therefore, the exact formulas for efficiency depend on the purpose of the machine. What's the difference in the maximal efficiency of a heat pump and a heat engine? Both the engine and the pump have the cold reservoir set at {eq}T_c =10^{\circ} C {/eq} and the hot reservoir at {eq}T_h = 70^{\circ} C {/eq}.
Heat Pump:
The heat pump is defined as the mechanical machine, which is used for the heat transfer from a colder region to a hotter region. It utilized for heating purposes, and its function is just the opposite of the refrigerator.
