Consider the heat engine operating at steady state between the two thermal reservoirs shown at the right while producing a net power output of 700 kW. If 1000 kW of heat (Q̇H) is transferred to the heat engine from a thermal reservoir at a temperature of TH = 900 K, and heat is rejected to a thermal reservoir at a temperature of TL = 300 K, is this heat engine possible?
