diameter of a vertical shaft turbine is 450 rpm at the inlet. The width of the runner at the inlet is 50 mm. The diameter and width at the outlet are 300 mm and 75 mm, respectively. The blade occupies 8% of the circumference. The guide vane angle is 24o , the inlet angle of the runner blade is 95o and the outlet angle is 30o . The fluid leaves the runner without whirl. The pressure head at the inlet is 55 mm above that at the exit from the runner. The fluid friction losses account for 18 % of th
