Description

This accessory comprises a miniature Pelton wheel with a spear-valve arrangement mounted on a support frame which fits onto the hydraulics bench top channel. Mechanical output from the turbine is absorbed using a simple friction dynamometer. Pressure at the spear-valve is indicated on a remote gauge.

A non-contacting tachometer is supplied which will be used to determine the speed of the Pelton wheel. Basic principles of the Pelton turbine may be demonstrated and with appropriate measurements, power produced and efficiency may be determined.
