the first compressor stage at 100 kPa, 290 K. After passing an intercooler operating at 600
kPa, air enters the second compressor stage at 480 K. The pressure ratio across the two
compressor stages is 10. The isentropic efficiency of both compressor stages is 85%. At the
inlet of each turbine stage, the temperature is 1500 K and after the second turbine stage, the
pressure returns to 100 kPa. The isentropic efficiency of both turbine stages is 90%. The
second combustor operates at 400 kPa. The regenerator effectiveness is 70%. Determine:
a) The heat transfer rate in the intercooler per unit of mass flowing
b) The temperature of the air at the inlet of the first combustor
c) The tmperature of the air at the outlet of the regenerator (stage 10)

At the beginning of the compression process, air is at 95 kPa and 27°C, and 760 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Take into account the variation of specific heats with temperature. The gas constant of air is R = 0.287 kJ/kg-K.
