A heat engine produces 12 MW of power while rejecting 875 kW

A heat engine produces 1.2 MW of power while rejecting 875 kW to the environment. What is the rate of heat transfer from the high temperature source to the heat engine?

Solution

the rate of heat transfer from the high temperature source to the heat engine is given by

H = (1.2*10^6)/(1.2*10^6+875*10^3) = 0.5783
