A reaction turbine has guide vanes at an angle of 30° and the runner blades make an angle of 80° relative to the tangent at inlet. The blades width at the inlet is 1/4 of the outer diameter. The water does not have any tangential velocity at the outlet. The head is 25 m and the rotational speed of the runner is 16.67 rotations per second. The turbine efficiency is 88 %. Determine the turbine runner diameter at the inlet and the power developed.
