1. À Pelton wheel performance data are collected in the following table. Turbine speed (RPM) 3000 Shaft torque (Nem) 2.4 Water supply line Water flow pressure (bar) rate (L/min) 18.4 If water supply pipe diameter is 25 mm and turbine wheel diameter is 70 mm, calculate the hydraulic head in m, jet velocity in m/s, speed ratio, hydraulic power in W, mechanical power in W and efficiency of the turbine. What is the optimum speed (RPM) of the wheel (for maximum power)?
