C.V. Ideal compressor, inlet: 1 exit: 2
Adiabatic : q = 0.
Reversible: sgen = 0
The ideal nozzle then expands back down to state 1 (constant s). The actual compressor discharges at state 3 however, so we have:
wC = wCs/ηC = -157.18 ⇒ T3 = T1 - wC/Cp = 446.6 K
Nozzle receives air at 3 and exhausts at 5. We must do the ideal (exit at 4) first.
