Irreversible process is the correct answer.

If these processes are non-flow processes then we can call them reversible process.

@All.

The otto and diesel cycles are irreversible so the constant pressure and constant volumes are irreversible processes.

VRC said:   9 years ago
The constant pressure, constant volume and constant pvn processes are regarded as REVERSIBLE process. So, the answer is B.

S Bera said:   8 years ago
Const pressure Const volume. Polytropic process are non-flow reversible process. So false is the correct answer.

Deepak said:   8 years ago
Constant pressure, Constant volume, and polytropic process (PV^n) is REVERSIBLE.

The correct answer is FALSE.

Throttling process and expansion process are irreversible process. But CV and cp and CT are reversible process.

Sai said:   6 years ago
No, the Constant pressure process practically not possible. Only throttling process is irreversible process.

Anshul said:   9 years ago
It should be false because for air standard cycles all processes except Throttling process are reversible.

Is that these processes can not back their initial stage then which process get back their initial stage.

Jay said:   5 years ago
The answer is wrong. All the process like constant pressure, constant volume are a reversible process.
