What is a turbine
turbine is a Rotary mechanical device that extract energy from a fast moving flow of water gas air or other fluid and convert into useful work
A turbine is a turbo machine at least one moving parts called a rotor assembly which is a shft or drum with blades attached
Moving fluid at On The Blade so that they move and impart rotational energy to Rotor

Working Principle
The working principle is very much simple
When the fluid strike the Blades of the turbine the blades are displaced which produce rotational energy
When the turbine shaft is directly coupled to an electric generator mechanical energy is converted to electrical energy
This electrical power is known as hydroelectric power

Impulse turbine
》In an impulse turbine fast moving fluid is fired through narrow nozzle at the turbine blades to make them spin around
》 The Blades of an impulse turbine are usually bucket shape so they catch the fluid and direct it off at an angle
》 In an impulse turbine the fluid is post to write the turbine at high speed

Types of impulse turbines
🔘Pelton turbine
🔘Cross flow turbine
🔘Pelton turbine
🔘Cross flow turbine
Pelton wheel
🔘 These are usually used for hi head low flow power plants
🔘 It was invented by Lester Ella Pelton in the 1870
🔘 Nozzle are direct forcefull high speed stream of water against a Rotary series okpunjab bucket also known as impulse blades which are mounted around the circumferential Rim of a driver Wheel also called a runner.
🔘 As the water jet hit the bucket blades the direction of water velocity is changed to no the contours of the bucket.
🔘 Water impulse energy exerts torque on the bucket and Wheel system spinning the wheel the water stream itself does a U turn and exit at the outer side of the bucket.
🔘 Pelton wheel operate best with drop height (50-200m) and flow rate is (4-15m3/s)

Applications
🔘 Pelton wheel are the preferred turbine for hydro- power , when the available water source has relatively high hydraulic head at low flow rate
🔘 Pelton wheel are made in all size . For maximum power and efficiency , the wheel and turbine system is designed such that the water jet velocity is twice the velocity of the rotating buckets.
🔘There exist in multi ton pelton wheel mounted on vertical oil pad bearing in hydraulic power .
