Steam initially at 8 MPa and 600 ⁰C expands in a two-stage adiabatic turbine entering it with a mass flow rate of 13 kg/s as shown in the figure below. Some steam in the form of saturated vapor at 0.3 MPa is extracted at the end of the first stage with a mass flow rate of 1.3 kg/s, while the remaining part enters the second stage. At the end of the second stage, a saturated mixture with a quality of 0.85 at 10 kPa is produced. Calculate the power output of this turbine.
