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. TECHNICAL SPECIFICATIONS Speed range: 0-1800 rpm Brake power: 10W Pressure gauge range: 0-1 Bar / 0-15 PSI Force balance range: 2×0-20 N spring balance Number of Pelton buckets: 24 Diameter of Pelton wheel: 130mm Requires Hydraulics Bench Service unit F1-10/F1-10-2 EXPERIMENTAL CONTENT To determine the operating characteristics of a Pelton Turbine Performance charts of power, speed, torque and efficiency Turbine output torque v rotor speed Turbine output power v rotor speed Turbine overall efficiency v rotor speed
