3. INTERODUCTION
Water turbine is a rotary engine that takes energy from moving water. Water turbine were developed in the nineteenth century and were widely used for industrial power prior to electrical grids. Now they are mostly used for electric power generation. They harness a clean and renewable energy source.

4. HISTORY
Water wheels have been used for thousand of years for industrial power. Their main shortcoming is size,which limits the flow rate and head that can be used. The word turbine was copied by the french engineer Claude Bourdin in the early 19th century and its derived from the latine word for “whirling” or a “vortex”.

5. TIMELINE
In 1820, Jean-Victor Poncelet developed an inward-flow turbine.
In 1826, Benoit Fourneyron developed an outward-flow turbine.
In 1844, Uriah A. Boyden developed an outward-flow turbine that emproved on the performance of the Fourneyron turbine.
In 1849, James B. Francis improved an inward-flow reaction turbine to over 90% efficeincy.
Around 1913,Vector Kaplan created the Kaplan turbine, a propeller-type machine.

6. Structure of Water turbine

7. THEORY OF OPERATION
Flowing water is directed on to the blades of a turbine runner, creating a force on the blades. Since the runner is spining , the force acts through a distance. In this way, energy is transferred from the water flow to the turbine.

8. How a Hydroelectric Power System Works - Part 1
Flowing water is directed at a turbine (remember turbines are just advanced waterwheels). The flowing water causes the turbine to rotate, converting the water’s kinetic energy into mechanical energy.

9. How a Hydroelectric Power System Works – Part 2
The mechanical energy produced by the turbine is converted into electric energy using a turbine generator. Inside the generator, the shaft of the turbine spins a magnet inside coils of copper wire. It is a fact of nature that moving a magnet near a conductor causes an electric current.

10. How a Hydropower System Works
Flowing water is directed at a turbine which (inside the generator) spins a magnet inside coils of copper wire. This produces an electric current.

11. TYPES OF GROUP
Reaction Turbine- acted on by water, which changes pressure as it moves through the turbine and give up its energy.
Impulsion Turbine- change the velocity of wate jet. The jet pushes the turbine’s curved blades which reserve the flow.

12. Hydropower is an important renewable energy source world wide...

13. Even here
in our desert home,
we can experience new, renewable technologies with the power of water!
