Air at a molar flow rate of $n,$ temperature of $T_1$ and pressure of $P_1$ is compressed to $P_2$ by

compressor having an efficiency $.$ Calculate the power required for the compressor and the

temperature of the outlet stream.

a$)T_1=25C,P_1=101\mathrm{.}33$kPa,$n=100mo\frac{l}{s},P_2=375$kPa,$=0\mathrm{.}75$

b$)T_1=80C,P_1=375$kPa,$n=100mo\frac{l}{s},P_2=1000$kPa,$=0\mathrm{.}70$

c$)T_1=30C,P_1=100$kPa,$n=150mo\frac{l}{s},P_2=500$kPa,$=0\mathrm{.}80$

d$)T_1=100C,P_1=500$kPa,$n=50mo\frac{l}{s},P_2=1300$kPa,$=0\mathrm{.}75$
