A process during which the entropy remains constant is called an isentropic process, written = or =. [12] Some examples of theoretically isentropic thermodynamic devices are pumps, gas compressors, turbines, nozzles, and diffusers.
Isentropic is the combination of the Greek word "iso" (which means - same) and entropy. When the change in flow variables is small and gradual, isentropic flows occur. The generation of sound waves is an isentropic process. A supersonic flow that is turned while there is an

In an isentropic process, system entropy (S) is constant. Under these conditions, p 1 V 1 γ = p 2 V 2 γ , where γ is defined as the heat capacity ratio , which is constant for a calorifically perfect gas .
Isentropic : The process is one of constant entropy (=, =). It is adiabatic (no heat nor mass exchange) and reversible. It is adiabatic (no heat nor mass exchange) and reversible. Isenthalpic : The process that proceeds without any change in enthalpy or specific enthalpy.
For an ideal gas, an isentropic process has: ... determine the speed of sound (pressure waves), according to the Newton-Laplace formula =. In solids, ...
In an isenthalpic process, the enthalpy is constant. [2] A horizontal line in the diagram represents an isenthalpic process. A vertical line in the h–s chart represents an isentropic process. The process 3–4 in a Rankine cycle is isentropic when the steam turbine is said to be an ideal one. So the expansion process in a turbine can be ...
If a steady-state, steady-flow process is analysed using a control volume, everything outside the control volume is considered to be the surroundings. [2]Such a process will be isenthalpic if there is no transfer of heat to or from the surroundings, no work done on or by the surroundings, and no change in the kinetic energy of the fluid. [3]
