Which efficiency loss occurs when an irreversible cycle operates?

A)Entropy generation within the working fluid
B)Excessive control system energy usage
C)Insufficient lubricant thermal conductivity
D)Increased thermal expansion of components

💡 Explanation

When irreversible cycles such as diesel engines have entropy generation, work potential decreases because less heat converts to useful work through viscous effects and friction; therefore available work is reduced rather than other factors like thermal expansion, whose effects are secondary.
