Irreversible process examples

WebAdiabatic, irreversible processes between the same initial state and final volume always yield lower work. This is a useful criterion to determine when an adiabatic process is irreversible: • The process is reversible if dU + p · dV = 0. • The process is irreversible if dU + p · dV > 0. • The process is not feasible if dU + p · dV < 0.
