Steam enters a turbine steadily at 7 mpa and 600°c with a velocity of 60 m/s and leaves at 25 kpa with a quality of 95 percent. a heat loss of 21 kj/kg occurs during the process. the inlet area of the turbine is 150 cm2, and the exit area is 1400 cm2. the specific volumes and enthalpies are v1 = 0.05567 m3/kg, h1 = 3650.6 kj/kg, v2 = 5.8933 m3/kg, and h2 = 2500.2 kj/kg. determine

(a) flowrate of the steam,
(b) exit velocity, and
(c) the power output.
