Problem $2-1.$ In a Rankine cycle with one stage of reheat, steam enters the turbine at $130lb\frac{f}{i}{n}^2$

and $950F$ and condenses at $100F.$ The cycle produces $1\mathrm{.}7(10{)}^{9}Bt\frac{u}{h}r$ and has one stage of

reheat, optimally placed, back to $950F.$ One feedwater of the closed type with drains cascaded

back to the condenser receives bled steam at the reheat pressure. The high$-$ and low$-$ pressure

turbine sections have isentropic efficiencies of $92\%$ and $90\%,$ respectively while the pump has

an isentropic efficiency of $75\%.$ Determine: $($a$)$ the appropriate reheat pressure, $($b$)$ the mass

flow rate of steam into the turbine kilograms per second, and $($b$)$ the cycle thermal efficiency.

Use TTD $=-2\mathrm{.}9F.$
