    Generally, hydraulic turbines are classified into two categories.

    1. Impulse turbine

    2. Reaction turbine

    The impulse turbine works on the principle of impulse, as its name suggest.

    In the impulse turbine, the head or pressure energy of water is first converted into kinetic energy by means of nozzle kept close to the runner.

    The nozzle produces a jet of higher velocity. This higher velocity jet is allowed to impinge on the set of buckets fixed on the outer periphery of the runner or wheel. This bucket on wheel changes the direction of jet.

    The change of momentum of water causes the wheel to rotate and produces mechanical energy.
