$1.00
Air at 30 °C and 120 kPa enters a compressor operating at steady state and exits at 250 °C and 620 kPa. Stray heat transfer and kinetic and potential energy effects are negligible.
Determine the:
a. Temperature in degrees K at the exit of the compressor if the compressor operates
isentropically, i.e. T2s
Ans. 484.6 K
b. Isentropic compressor efficiency Ans. 82.5%
