A Francis radial-flow turbine has a runner inlet radius of 2.75 m and its outlet radius is 1.85 m. The runner blade widths are 0.9 m and 2.93 m at the inlet and outlet, respectively. The runner must rotate at 150 rpm to turn the 60-Hz electric generator. The wicket gates turn the flow by angle 35° from radial at the runner inlet, and the flow at the runner outlet is to have angle 20° from radial for proper flow through the draft tube. The volume flow rate at design conditions is 514 m3/s, and the gross head provided by the dam is 100 m. Determine the tangential component of the water velocity at the outlet in m/s.
