An engine draws energy from a hot reservoir with a temperature of 1250 K and exhausts energy into a cold reservoir with a temperature of 378 K. Over the course of one hour, the engine absorbs 1.42 × 10^5 J from the hot reservoir and exhausts 7.5 × 10^4 J into the cold reservoir.
a. What is the power output of this engine?
b. What is the maximum (Carnot) efficiency of a heat engine running between these two reservoirs?
c. What is the actual efficiency of this engine?
Answers: 1
