Which efficiency loss occurs when an irreversible cycle operates?

💡 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.
