The theoretical slope is determined from Equation 5, as follows. You should collect water for at least one minute to minimize timing errors. This is achieved by closing the ball valve and measuring the time that it takes to accumulate a known volume of fluid in the tank, as measured from the sight glass. The nuts should only be tightened enough to level the plate.Ĭheck that the position is correct by gently oscillating the pan. The impact of the water on the vanes generates a torque on the wheel, causing it to rotate and to generate electricity.Īn air vent at the top of the cylinder maintains the atmospheric pressure inside the cylinder.Ī weight pan is mounted at the top of the stem to allow the force of the striking water to be counterbalanced by applied masses 5.ĭo not overtighten the knurled nuts, as this will damage the top plate. Turbines rotate due to force exerted by one or more water jets that are directed tangentially onto the turbines vanes or buckets. For example, in hydropower plants, turbines are utilized to generate electricity.
