An impulse turbine is a turbine that is driven by high velocity jets of water or steam from a nozzle directed on to vanes or buckets attached to a wheel. The resulting impulse (as described by Newton’s second law of motion) spins the turbine and removes kinetic energy from the fluid flow.
Impulse Turbine also known as Velocity Turbine, Kinetic Turbine.
Examples:- Pelton Turbine and propeller Turbine
