Superheated steam at 20 bar and 380?C enters a steam turbine with a velocity of 60 m/s. The pressure, quality and velocity of the water at the discharge section of the turbine are 0.75 bar, 0.95, and 200 m/s, respectively. The entrance section of the turbine has an area of 0.025 m2 and it is 3 m above the exit section. The rate of heat loss from the turbine casing to the surroundings is 8.5 kW. Calculate (a) the mass flow rate (kg/s) of the steam, and (b) the power output (MW) of the turbine.
