Question $2$: $[25$ points$]$

Use Gyftopoulos' water property tables and the property interpolator you developed for use in this class. In the final stages of expansion of a steam turbine powerplant turbine inlet is at $10$MPa and $500$degC.Condenser temperature is $45$ deg C $.$ Evaluate turbine power in $M\frac{J}{k}g($assume mas flow rate is $1k\frac{g}{s})$ if turbine isentropic efficiency is $0\mathrm{.}91.$ Steps:

$($a$)$ Draw the block diagram for the expansion process

$($b$)$ Draw the T$-$S diagram.

$($c$)$ Evaluate turbine specific power in $M\frac{J}{k}g($mass flow rate $1k\frac{g}{s}$ and the isentropic efficiency is $0\mathrm{.}91).$

$($d$)$ Evaluate the specific entropy generated by irreversibility in this expansion process.
