Entropy Analysis of a Heat Engine Consider a 35% efficient heat engine operating between a large, high-temperature reservoir at 1000 K (727 °C) and a large, cold reservoir at 308 K (35°C). A. If it withdraws 1.2 MJ/s from the high-temperature reservoir, what would be the rate of loss of entropy from that reservoir and what would be the rate of gain by the low-temperature reservoir? B. Express the work done by the engine in watts. C. What would be the total entropy gain of the system? D. Determine Carnot efficiency and recalculate the a, b, and c, accordingly.
