The Apparatus of Pelton turbine mounts on the base. Pelton turbine is mounted on a transparent Plexiglass Hosing. A adjustable water spear valve allow the water to leave through the nozzle and hits the buckets. An adjustable spear valve controls the discharge by varying the diameter of the jet from the nozzle. The Hydraulic Bench supplies water to the nozzle. Water from the turbine discharges back into the base unit tank and recalculates. This demonstration Pelton Turbine is 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 manometer gauge. A non-contact tachometer may be used to determine the speed of the Pelton wheel turbine. Basic principles of the Pelton wheel turbine may be demonstrated and with appropriate measurements, power produced and efficiency may be determined.
