Please do part (c) Please do part (c) 7.27. An expander operates adiabatically with nitrogen entering

7.27. An expander operates adiabatically with nitrogen entering at T1 and P1 with a molar flow rate n. The exhaust pressure is P2, and the expander efficiency is . Estimate the power output of the expander and the temperature of the exhaust stream for one of the following sets of operating conditions. (a) T1=480C,P1=6bar,n=200mols1,P2=1bar,=0.80 (b) T1=400C,P1=5 bar, n=150mols1,P2=1bar,=0.75 (c) T1=500C,P1=7 bar, n=175mols1,P2=1bar,=0.78 (d) T1=450C,P1=8 bar, n=100mols1,P2=2bar,=0.85 (e) T1=900(F)P1=95(psia),n=0.5(lbmol)(s)1,P2=15(psia),=0.80
