Hydraulic turbines : is a prime mover that uses the energy of the flowing water and converts it into the mechanical energy.
This type of energy source is a renewable source which is free from environmental pollution , and can be classified into two types according to the head and quantity of water available and they are
1- Impulse turbine : works in the high head of water and small quantity of flow, and the Pelton turbine is an real example of Impulse turbines.
2-Reaction turbine : works with the low head of water and large flow , and the Francis and Kalpan turbines are real examples of reaction turbines.
1::: Pelton turbines :
Is an impulse turbine which converts the pressure energy of water into kinetic energy, when forms the high velocity jet of water with can drive the wheel , and consists of the following parts :
A) Roter B) Nozzle. C) A needle spear D) Buckets. E) Runner F) Brake nozzle G) Casing
