Question 1. 40 kg/s of saturated liquid water at 250 degree C (8u cam throttled to 100 °C (stream 2). The portion of stream 2 resulting from this throttling process that is a saturated vapour (stream 3) enters an adiabatic turbine as shown in the figure below. Water leaves the turbine at 20 kPa and a quality of 7%. Determine: (a) the pressure and the quality (if a mixture) at the throttling valve exit (that is,stream 2), (b) the power output of the turbine (in kW).
