Web5 Answers. Yes. where the equality holds in the reversible case. So, a reversible adiabatic process is necessarily isentropic, but irreversible adiabatic processes are not so. To put it in another way, in an irreversible process, according to the above inequality, either entropy changes, or heat must be somehow removed from the system to make ... WebSince no energy is dissipated as heat an isentropic process is both adiabatic and reversible. Steady state fluid systems are often best represented as adiabatic, but to give an estimation of the efficiency of the process the isentropic performance of a system is often related to the adiabatic or actual performance. bringing up father tv showWebApr 28, 2024 · Isentropic efficiency relates actual compression with an ideal compression that does not exchange heat with the environment, (adiabatic) and does not create any losses (no viscosity and reversible).
