Question

Steam enters an adiabatic turbine at a rate of 10 kg/s at 3.5 MPa, 350°C. At a point where the steam
is at 1 MPa, 250°C, 15% of the total mass is extracted and used to preheat water entering a boiler.
The remainder of the steam is expanded further and exhausted from the turbine at 30 kPa with a
quality of 90%. Determine the power output of the turbine.
