Question

A heat engine is used to drive a heat pump. the heat transfers from the heat engine (he) and from the heat pump (hp) are used to heat the water circulating through the radiators of a building. the efficiency of the he is 27 % and the cop of the hp is 4. evaluate the ratio of heat transfer to the circulating water to that of to the heat engine

Answer 1

The ratio is obtained by dividing formula
Of heat engine and heat pump
W/q2-q1=q2-q1/t2-t1
