Steam enters a turbine steadily at 7 mpa and ‘w 600c c with a velocity of 60 m/s and leaves at 25 kpa with a quality of 95 percent. a heat loss of 20 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, and (c) the power output.

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
