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.
