Pelton turbine is a tangential flow impulse turbine in which the pressure energy of water is converted into kinetic energy to form high speed water jet and this jet strikes the wheel tangentially to make it rotate. The fluid power is converted into kinetic energy in the nozzles.
Pelton wheel definition is an impulse turbine or waterwheel consisting of a row of double cupshaped buckets arranged around the rim of a wheel and actuated by one or more jets of water playing into the cups at high velocity.
