Q$-4(30$ pts$.)$ Superheated steam enters a turbine at $2$MPa and $600C$ and exits at $10$kPa. For a steam mass flow rate of $2k\frac{g}{s},$ determine

$($a$)(15$p$)$ turbine inlet and isentropic exit conditions $($temperature$,$ enthalpy, entropy and phase. Also vapor quality if it's mixture$)$

$($b$)(5$p$)$ maximum power output in hp $($isentropic case$)$

$($c$)(10$p$)$ turbine outlet conditions $($phase and temperature$)$ if the turbine has an isentropic efficiency of $77\mathrm{.}5\%$
