Current Attempt in Progress

Steam enters a turbine operating at steady state at $850\backslash$deg F and $450$lb$($f$)/($i$)$n$^(2)$ and leaves as a saturated vapor at $0\mathrm{.}8$lb$($f$)/($i$)$n$^(2).$ The turbine

develops $12,000$hp$,$ and heat transfer from the turbine to the surroundings occurs at a rate of $2\backslash$times $10^(6)$Bt$($u$)/($h$).$ Neglect kinetic and

potential energy changes from inlet to exit.

Determine the exit temperature, in $\backslash$deg F$,$ and the volumetric flow rate of the steam at the inlet, in f$($t$^(3))/($s$).$
