About PELTON WHEEL TURBINE DEMONSTRATION
Specification:
PELTONWHEEL TURBINE DEMONSTRATION
This accessory comprises a miniaturePelton wheel with spear-valve arrangement mounted on a support frame, whichfits on to the Hydraulics Bench top channel. Mechanical output from the turbineis absorbed using a simple friction dynamo meter. Pressure at the spear valveis indicated on a remote gauge.
A non-contacting tachometer may beused to determine the speed of the Pelton wheel. Basic principles of the Peltonturbine may be demonstrated and, with appropriate measurements, power producedand efficiency may be determined.
