Let us consider the heat engine which receives a heat transfer rate of 1 MW at a high temperature of 823 K and rejects energy to the ambient surroundings at 300 K. Work is produced at a rate of 450 kW.
(a) How much energy is discarded to the ambient surroundings?
(b) What is the engine efficiency?
(c) Compare the results to those of a Carnot heat engine under the same conditions. How much energy can be saved if we use a Carnot heat engine?
