Steam enters a turbine steadily at 10 mpa and 550°c with a velocity of 60 m/s and leaves at 25 kpa with a quality of 95%. a heat loss of 30 kj/kg occurs during the process. the inlet area of the turbine is 150 cm², and the exit area is 1400 cm². determine: (a) the mass flow rate of the steam. (b) the exit velocity. (c) the power output.
