What is meant by reversible engine? Explain, why the efficiency of a reversible engine is maximum.

Text Solution

Verified by Experts

The correct Answer is:
The engine, in which the process can be retraced at any stage of its operation by reversing the boundary conditions, is called a reversible heat engine. Its efficiency is maximum, as no dissipation of energy takes place against friction, etc in such a heat engine.
