A Pelton wheel works under a head of 425 m and rotating at 720 rpm. Determine the power produced and the hydraulic efficiency when the discharge through the machine is 0.3 m3/s and the jet is deflected by 165°. Also find the jet ratio and overall efficiency. Assume coefficient of velocity as 0.97, speed ratio as 0.46 and the blade velocity coefficient as 0.9.
