An inward-flow reaction turbine has an inlet guide vane angle of 30◦ and the inlet edges of the runner blades are at 120◦ to the direction of whirl. The breadth of the runner at inlet is a quarter of the diameter at inlet and there is no velocity of whirl at outlet. The overall head is 15 m and the rotational speed 104.7 rad ·s−1 (16.67 rev/s). The hydraulic and overall efficiencies may be assumed to be 88% and 85% respectively. Calculate the runner diameter at inlet and the power developed. (The thickness of the blades may be neglected.)
