Question #$2$

Dry saturated steam at $p_1=3\mathrm{.}5$MPa is contained in a cylinder$-$piston arrangement. It is

brought into thermal contact with a heat sink at $T_R=175C.$ The steam rejects $Q_{12}=16MJ$

of heat during a constant pressure process. The mass of steam is $m=10kg.$ Determine $($a$)$

final state $\text{'}2\text{'}$ of steam, $($b$)$ change in entropy of steam $(S_{12}),$ and $($c$)$ change in entropy of

the universe $(S_U).$
