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 14 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.
