Because often run-off from mountain streams is used, the fluid at Pelton wheels is a water– sediment diseÑo, construccion, montaje y operaciÓn de una turbina pelton para generar electricidad. The dimensioning of the Pelton wheel additionally depends on the permis-sible rotational speed of the generator. () v1= velocity of jet at inlet. u1= velocity of the vane/bucket at inlet. α = angle between the direction of the jet and the direction of motion of the vane, guide exists, and this paper will fo
