Air at 25 °C and 100 kPa enters a compressor operating at steady state and exits at 260 °C and 650 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 b. Isentropic compressor efficiency using enthalpies c. Isentropic compressor efficiency using temperatures and assuming constant specific heat, cp.
