Compressor work = (P2V2 - P1V1)/(1 - γ) Where γ = specific heat ratio As this formula represent work done by gas so inversely we can say work done by compressor. Method-3: compressor power = mCvdT Where Cv = specific heat at constant volume We know dq = du + dw. Here dq = 0 since it is isentropic process. So dw= -du and du = mCvdT.
