Current Attempt in Progress

Steam enters a turbine operating at steady state at $750F$ and $450lb\frac{f}{i}{n}^2$ and leaves as a saturated vapor at $0\mathrm{.}8lb\frac{f}{i}{n}^2.$ The turbine

develops $12,000hp,$ and heat transfer from the turbine to the surroundings occurs at a rate of $2{10}^{6}Bt\frac{u}{h}.$ Neglect kinetic and

potential energy changes from inlet to exit.

Determine the exit temperature, in $F,$ and the volumetric flow rate of the steam at the inlet, in $f\frac{t^3}{s}.$
