The penstock redirects water 180 degrees to distribute flow to a hydroelectric turbine generator. This change in direction causes a reaction force Fy of 830 kN. The inside diameter of the pipe is 1.4 m Determine (a) the flow rate in cu. m/s, (b) the total power of the flow in MW and (c) the minimum height of water above the penstock in meters. The density of water, rho, is 1000 kg/cu. m. Derive (b) only and express the algebraic solution in terms of Fy, dia and rho.

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.
