WebFirstly, the compression process in the reversible Carnot cycle involves the wet compression of the liquid-vapor mixture. In practice, when a reciprocating compressor is used, wet compression is not found suitable. After evaporation of refrigerant, it … WebConsider a reversible cyclic process, consists of many Carnot cycles. In going from point A to B and then back A, all the closed paths cancel each other that results in parent path ABA. Figure 3. A cyclic process made of many Carnot cycles.

WebThe term isentropic which means constant entropy, is used to describe a reversible cycle that is adiabatic (i.e., no heat transfer). From the perspective of the gas turbine cycle, air enters the compressor at the atmospheric pressure and gets compressed around 10–23 times its initial value. In science, a process that is not reversible is called irreversible. This concept arises frequently in thermodynamics. All complex natural processes are irreversible, although a phase transition at the coexistence temperature (e.g. melting of ice cubes in water) is well approximated as reversible. In thermodynamics, a change in the thermodynamic state of a system and all o…

WebJun 13, 2024 · Figure 7. Reversible versus irreversible expansion of an ideal gas. In contrast, an irreversible expansion corresponds to movement of the piston when Pgas > Papplied, or equivalently, − Pgas < − Papplied. Therefore, the work done on the gas is less in the reversible case than it is in the irreversible case. (Both work terms are less than zero. WebAn irreversible process that is not reversible.
