www.ltu.sePelton turbine (jet diameter and hydraulic efficiency – From Hydromekanik, H. Gustavsson) A Pelton turbine with a head H=360 m and an efficiency η of 85 % develops a power P=4500 kW. The . runner is driven by two water jets at 400 rpm. The losses in the nozzle are 3 % and the friction coefficient of .

PELTON TURBINE TEST - btu.edu.tr
depo.btu.edu.trThe Pelton Turbine is a hydraulic ‘impulse’ turbine, in which one or more water jets hit ‘buckets’ on a wheel. The force produced by the jet impact at right angles to the buckets generates a torque that causes the wheel to rotate, thus producing power. The name ‘Pelton’
