1. The problem statement, all variables and given/known data
Consider a 210MW steam power plant that operates on a simple Rankine cycle. Steam
enters the turbine at 10MPa and 500°C and is cooled in the condenser at a pressure of10kPa. The adiabatic efficiency of the turbine and pump is 85% (a) the quality of the steam at
the turbine exit.

2. Relevant equations
x=($\frac{So-Sf}{Sfg}$)

3. The attempt at a solution
x=($\frac{6.6-0.65}{7.5}$)
=0.8

but the right answer is 0.874

Found the solution already, thank you
