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.

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
