WebSep 9, 2024 · In a reversible process, every intermediate state between the extremes is an equilibrium state, regardless of the direction of the change. In contrast, an irreversible process is one in which the intermediate states are not equilibrium states, so change occurs spontaneously in only one direction. WebJan 18, 2024 · What, if any, is the difference in net work done by the gas if the isochoric heat addition was irreversible instead of reversible? Consider a reversible ideal gas cycle consisting of: 1. An isochoric heat addition, 2. An isothermal expansion to the initial pressure, and 3. An isobaric compression to the initial volume.

Web$\begingroup$ Suppose you are operating your process in a cycle where $\Delta U$ and $\Delta S$ are both zero. Both the reversible process and the irreversible process start and end at the same state. The irreversible process uses a great big cycle with large W and large Q, while the reversible process uses a tiny little cycle with small W and small Q. 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.

WebThe irreversible compression and expansion processes take place through lines 1 → 2 and 3 → 4, respectively. The dotted lines 1 → 2s and 3 → 4s show the isentropic compression and expansion processes.
