We are offering water turbine model : this model to show the conversion of mechanical energy into electrical energy by using it as a water turbine to drive a dynamo for producing electricity. The plastic impeller housed in a cast metal casing with a clear perspex front that allows viewing of its functioning. The inlet tube provided at the top and outlet tube on the side, both tubes riffled for tubing connectors. A dynamo mounted along the impeller shaft glows the led indicating the conversion of mechanical energy to electrical energy.
