Noun
Pelton wheel (plural Pelton wheels)
(hydroelectricity) A form of impulse turbine or water wheel, extracting energy from the impulse of moving water

Applications Pelton wheels are the preferred turbine for hydro-power, when the available water source has relatively high hydraulic head at low flow rates, where the Pelton wheel geometry is most suitable. Source: Internet
As the equations indicate, when a real Pelton wheel is working close to maximum efficiency, the fluid flows off the wheel with very little residual velocity. Source: Internet
Compared to other turbine designs, the relatively low specific speed of the Pelton wheel, implies that the geometry is inherently a "low gear" design. Source: Internet
