For an adiabatic gas compressor, the efficiency with respect to isentropic operation η is a measure of internal irreversibilities; so is the dimensionless rate of entropy generation S_G /R ≡ Ṡ_G /(ṅ R). Assuming that the gas is ideal with constant heat capacities, show that η and S_G /R are related through the expression:

Where

π ≡ (P₂ / P₁)^R/^C_P
