The Demonstration Pelton Turbine provides a simple low cost introduction to turbine performance.This accessory comprises a miniature Pelton wheel with spear valve arrangement mounted on a support frame which locates on 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 (not supplied) may 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.

RANGE OF EXPERIMENTS

• Determining the operating characteristics, i.e. power, efficiency and torque, of a Pelton turbine at various speeds

UTILITIES REQUIRED

• Hydraulic Bench
