A schematic representation of a jet engine is presented in Figure. Flow of air at 50 kPa and
-16 °C enters compressor (state 1 in figure) and then it leaves from compressor at 2850 kPa
and 560 °C (state 2 in figure). After combustion, air flow enters the turbine at 1250 °C and
2750 kPa (state 3 in figure) and then it leaves from the turbine at 325 kPa and 650 °C (state 4
in figure). Finally, air flow leaves from the nozzle at 50 kPa and 420 °C (state 5 in figure).
Assume there is no heat transfer and neglect kinetic energy except out of the nozzle.
