An ideal gas (R= 0.2081 kJ/kgK, Cp=0.5203 ​​kJ/kgK, Cv=0.3122 kJ/kgK) at 90 kPa pressure and 25°C temperature at the inlet of an adiabatic compressor is compressed to 900 kPa. If the mass flow rate of the gas is 0.08 kg/s, find the isentropic efficiency of the compressor since 23.4 kW of compressor power is required.
