The following data are available for the turbine: Coefficient of velocity = 0.985 Angle of deflection of jet = 165° Speed ratio 0.46 Relative velocity at exit = Relative velocity at inlet Jet ratio 12 Compute the (a) hydraulic efficiency, (b) velocity of whirl at inlet and outlet, and (c) mean bucket speed. Assume zero frictional loss in the bucket.
