Answer» Air (ideal gas) enters a perfectly insulated compressor at a temperature of $310 K$ . The pressure ratio of the compressor of is $6$ . Specifci heat at constant pressure for air is $1005 J / k g . K$ and ratio of specific heats at constant pressure and constant volume is $1.4$ . Assume that specific heats of air are constant. If the isentropic efficiency of the compressor is $85$ percent, the difference in enthalpies of air between the exit and the inlet of the compressor is \(kJ/kg) (round off of nearest integer). 245
