Problem $08\mathrm{.}081-$ Determine the power output of the turbine.

Steam at $6$ MPa and $500C$ enter a two$-$stage adiabatic turbine at a rate of $15k\frac{g}{s}.$ Ten percent of the steam is extracted at the end of the first stage at a pressure of $1\mathrm{.}2$ MPa for other use. The remainder of the steam is further expanded in the second stage and leaves the turbine at $20$ kPa $.$ Use data from tables.

Problem $08\mathrm{.}081.$a $-$ Power output of a two$-$stage isentropic steam turbine

Determine the power output of the turbine, assuming the process is reversible.

The power output of the turbine in this case is $$ kW$.$
