Answer :
Mechanical work does the engine perform during each cycle 215 J.
The temperature of the low-temperature reservoir 377 K.
The thermal efficiency of the cycle is 0.39.
What is thermal efficiency?
The proportion of heat energy that is converted into work is known as a heat engine's thermal efficiency. The definition of thermal efficiency is. Even the most efficient heat engines have low efficiency typically below 50% and frequently much lower. Consequently, a significant amount of energy is wasted when heat engines release energy into the environment.
Mechanical work does the engine perform during each cycle = 550 - 335
= 215 joule.
The temperature of the low-temperature reservoir is 620 * 335/550
= 377 K
The thermal efficiency of the cycle is 1- (377/620)
= 0.39
