Compressors, Gas Turbines and Jet Engines
The overall isothermal efficiency of the compressor is defined as the ratio of

Isentropic power to the power required to drive the compressor
Volume of free air delivery per stroke to the swept volume of the piston
Work required to compress the air isothermally to the actual work required to compress the air for the same pressure ratio
