Consider an isentropic (idealistic adiabatic process, with no friction) process, in which the volume of a system is increased. For that to happen, the internal energy of the system would decrease because …

Jul 5, 2017 · In thermodynamics, an isentropic process is an idealized thermodynamic process that is adiabatic and in which the work transfers of the system are frictionless; there is no transfer of matter …

Aug 1, 2025 · 0 Since you said you already understand the derivation algebraically, the following is an attempt to explain the specific heat dependency by contrasting the isentropic process with the …

Sep 9, 2014 · This answer agrees with mine in that is states "approximately isentropic". The point I tried to make was that any lossy process is by definition isentropic - so this answer is looking at "how …

Mar 18, 2022 · What will the plot of an isentropic process for an incompressible substance look like on a T-S diagram?

Apr 11, 2023 · Trying to grasp why internal energy decreases in an isochoric, isentropic process Ask Question Asked 2 years, 8 months ago Modified 2 years, 8 months ago

Jul 20, 2022 · I know that isothermal compression work (input) is lesser than the isentropic/adiabatic compression work (input) for steady flow compressors. But does this also hold for positive …

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 …

Jul 21, 2022 · An isentropic process is by definition a reversible adiabatic process. A rapid process can be adiabatic simply because there is not enough time for energy transfer by means of heat to occur.

Question: The compression ratio of an air-standard Otto cycle is 10. Prior to the isentropic compression process, the air is at 100kPa,27°C and 400cm3 (the cylinder volume at BDC). The …
