An inventor claims to have invented a heat engine that operates using energy reservoirs whose temperatures are 600 K and 300 K. She also claims that this engine produces 10 kW of power while rejecting heat at a rate of 5 kW. a. What is the rate at which heat is being transferred from the high-temperature reservoir to this heat engine?
b. What is the engine's thermal efficiency?
c. What is the limit on the engine's thermal efficiency?
d. What is the maximum temperature the high-temperature reservoir can have such that this engine can operate without violating the second law or its corollaries while maintaining all other conditions the same?
e. Does this system satisfy the second law and all consequences of the second law?
