WebIn thermodynamics, an isentropic process is an idealized thermodynamic process that is both adiabatic and reversible. The work transfers of the system are frictionless, and there is no net transfer of heat or matter. Such an idealized process is useful in engineering as a model of and basis of comparison for real processes. This process is idealized because … WebA polytropic process is any thermodynamic process that can be expressed by the following equation: pV n = constant. The polytropic process can describe gas expansion and compression, which include heat transfer.The exponent n is known as the polytropic index, and it may take on any value from 0 to ∞, depending on the particular process.
