A compressor undergoes a reversible, steady flow process. The gas at inlet and outlet of the compressor is designated as state 1 and state 2 respectively. Potential and kinetic energy changes are to be ignored. The following notations are used:v = specific volume and P = pressure of the gas.The specific work required to be supplied to the compressor for this gas compression process is
