A gas stream flowing at $1mo\frac{l}{s}$ enters a steady$-$state turbineat $T_1=300K$

and $P_1=10$ bar and exits at $P_2=1$ bar. The turbine is adiabatic and

reversible.

A$)$ Write an energy balance on the turbine. Eliminate all terms that are

zero or negligible, but do not further simplify the remaining terms. Put

your final answer in a box.

B$)$ Write an entropy balance on the turbine. Eliminate all terms that are

zero or negligible, but do not further simplify the remaining terms. Put

your final answer in a box.

C$)$ Find the outlet temperature $T_2$ assuming that the gas is a pure ideal

gas with $Cp(IG)=30\frac{J}{m}ol$

D$)$ Find the outlet temperature $T_2$ assuming that the gas is an ideal gas

mixture of A and $B$ with $xA=0\mathrm{.}4,xB=0\mathrm{.}6,Cp(IG)=30\frac{J}{m}ol,$ and $Cp(IG)=$

$50\frac{J}{m}ol.$
