Demonstrates the working of water turbine for generation of electric power as in hydro-power stations. When water is made to fall on the vanes of turbine from inlet at the top, it makes the vanes of the turbine to rotate and escapes from the outlet at the bottom. A dynamo coupled to the shaft of the turbine rotates with it resulting in conversion of mechanical energy of rotation into electrical energy, which can be observed from the glow of indicator lamp. Both the inlet and outlet have serrated tubulatures for flexible tubing connections. Mounted on base.
