Steam enters a turbine steadily at 7 mpa and 600 degree celsius 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 cm^2, and the exit area is 1400 cm^2. determine (a) the mass flow rate of the steam (b) the exit velocity, and (b) the power output.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
