    rotated by the force generated in the vanes due to the momentum change or impulse which takes place as the jet strikes the vanes. Water turbines working on this impulse principle have been constructed with outputs of the order of 100‚000 kW and with efficiencies greater than 90%. In this experiment‚ the force generated by a jet of water as it strikes a flat plate‚ conical plate and hemispherical cup may be measured and compared with the momentum flow rate in the jet. 2.0 Experimental Design

    The Pelton wheel is a water impulse turbine. It was invented by Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water‚ as opposed to its weight like traditional overshot water wheel. Although many variations of impulse turbines existed prior to Pelton ’s design‚ they were less efficient than Pelton ’s design; the water leaving these wheels typically still had high speed‚ and carried away much of the energy. Pelton ’s paddle geometry was designed so that
