Water Circuit: Turbine

Principles of Science: Fluid Motion, Alternative Energy

Set the turbine in motion by forcing the water to hit the blades. As water hits them, the turbine is forced around.

The turbine can also be used to make water flow – essentially a pump. A spinning turbine will force stationary water to flow as it rotates through the water. Each blade is set at an angle so that as the blade turns, it forces the water to move.

This rotational motion can be used to power machinery; think of a propeller on a boat or even on an airplane. It can also be used to generate electricity if attached to an electrical generator. The energy of water flowing in a river can be used to turn a turbine and generate a safe and clean alternative form of energy. Hydroelectric power stations are currently being used around the world – two examples are the hydroelectric power stations at Niagara Falls and the Hoover Dam.
