Air with mass flow rate of 1 kg/s enters the first stage of a compressor at 100 kPa and 300 K and exit the second stage of the compressor at 2677 kPa. If the compressed air outgoing from the first stage of the compressor passes through an intercooler, then enters the second stage of the compressor at temperature 353 K. What is the indicated isothermal efficiency for the compressor assuming ideal compression process with polytropica index n = 1.3 for both stages, no pressure loss in the intercooler, and the pressure ratio across the first and the second stage of the compressor are equal?
