Compressors, Gas Turbines and Jet Engines The overall isothermal efficiency of the compressor is defined as the ratio of Isothermal power to the shaft power or B.P. of the motor or engine 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 Isentropic power to the power required to drive the compressor Isothermal power to the shaft power or B.P. of the motor or engine 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 Isentropic power to the power required to drive the compressor ANSWER DOWNLOAD EXAMIANS APP
