I read in Khurmi Book, he mentioned that all process is reversible other then polytropic, polytropic is an irreversible process.
As per Khurmi Answer is FALSE.
As per Khurmi Answer is FALSE.

Irreversibility is related to entropy, we can see the above-mentioned processes follow a curve in a T-s diagram and hence they are irreversible.

@ALL.
It is not pv power n it is pvn.
It is not pv power n it is pvn.

Constant pressure, Constant volume, and polytropic process (PV^n) is REVERSIBLE.
The correct answer is FALSE.
The correct answer is FALSE.

Const pressure Const volume. Polytropic process are non-flow reversible process. So false is the correct answer.

Practically they are irreversible but are considered Internally reversible like in reciprocaing engine. And that's why equation is defined for them and also these processes are shown by solid lines in diagrams.

Only throttling and free expansion process are the irreversible process. Except these all are the reversible process so the answer is false.
