A Brayton cycle operates with ideal air between 1 bar, 300 K and 5 bar, 1000 K. The air is compressed in two stages with perfect intercooling. Similarly in the turbine expansion occurs in two stages with perfect reheating. Calculate the optimum pressure in bar, network output and the fraction of turbine output that has to be put back to compressor (WC /WT )
