Pelton Wheel Turbine is only impulse water turbine now in common use, named in honour of Sir L. A. Pelton (1829-1908) of California, USA. It is a tangential flow impulse turbine. The water strikes the Buckets along the tangent of the runner. The energy available at the inlet of the turbine is only kinetic energy. The pressure at the inlet and outlet of the turbine is atmospheric. This turbine is used where water at high head is available. The main aim is to effectively understand the performance characteristics of a Pelton Wheel Turbine Test Rig. The other objective is to effectively understand the construction and operation of a Pelton Wheel Turbine. The turbine will be powered by a centrifugal pump, which will be driven electrically. The turbine output will be measured by a dynamometer. A water tank, piping, and other required accessories must be supplied with the test rig. Self-explanatory operating manuals must be provided with each system. Detailed theory, as well as practical exercises, will be included in the manual.
