TURBINES TURBINES

Hydraulic Turbines 1. Impulse Turbine – Pelton Wheel Potential energy of water is converted into kinetic energy by a set of nozzles 2. Reaction Turbine – Francis Turbine The water entering the runner possesses pressure which in turn does work on the vanes (blades) by the principle of reaction Specific Speed The speed at which the turbine run developing unit power under unit head.
