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’
