How Does An Impulse Turbine Work? Types of Impulse …

WebAn Impulse turbine is a type of turbine in which a high-velocity jet of water strikes the turbine blades and rotates the turbine to generate electricity. The impulse turbine works on the principle of Newton’s second law. Frenchmen Real and Pichon invented the compound impulse turbine in 1827. WebImpulse turbine works on the basic principle of impulse. When the jet of water strikes at the turbine blade with full of its speed, it generates a large force which used to rotate the turbine. The force is depends on the time interval and velocity of jet strikes the blades. This turbine used to rotate the generator, which produces electric power. greenville electric providers
