Determine wheel diameters at the pitch circle of blades, Mechanical Engineering

A pelton wheel works at the foot of a dam because of which the head available at the nozzle is 220m. the nozzle diameter is 20 c.m. and coefficient of speed 0.98. The wheel operates at 250 rev/min and generate 3.75 MW of power. Considering that blade angle at outlet is 16^o and jet ratio is 0.46. Determine wheel diameters at the pitch circle of blades, the hydraulic turbine efficiency and efficiency.
