Isentropic Efficiency in Engineering Thermodynamics Introduction
... Examples are also given in the text for the isentropic efficiencies of nozzles and compressors, but they are all similar to the turbine example shown. Once you accept that a flowing fluid can have the properties of an equilibrium state, the rest follows. We see that the isentropic approximation is p ...
