Afrancis turbine has a diameter of 1.4m and rotates at 430rpm. water enters the runner without shock with a flow velocity of 9.5 m/s and leaves the runner without whirl with an absolute velocity of 7m/s. the difference between the sum of the static and potential heads at entrance to the runner and at the exit from the runner is 62 m. if the turbine develops 12250kw and has a flow rate of 12m 3/s of water when the net head is 115m, find (a) the absolute velocity of the water at entry to the runner and the angle of the inlet guide vanes, (b) the entry angle of the runner blades and (c) the head lost in the runner.

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.
