WebThe following disadvantages of Impulse Turbine is: The installation cost is more. The bucket efficiency is low. The impulse turbine takes more space for installing as compared to the reaction turbine. Impulse turbine works only in high heads which is difficult to control. It has a low working speed. The water is admitted only in the form of jets. 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.

Webair passes over the turbine blade and the typical design of the turbine blade gives unidirectional rota-tion to the generator shaft. Hence, the turbines are called as ‘‘self-rectifying impulse turbine’’ or ‘‘bidirec-tional turbine’’. A bidirectional turbine needs guidevanes (GVs) placed up and down stream of the turbine blades or WebIn an ideal impulse turbine, the. A. Absolute velocity at the inlet of moving blade is equal to that at the outlet. B. Relative velocity at the inlet of the moving blade is equal to that at the outlet. C. Axial velocity at inlet is equal to that at the outlet. D. Whirl velocity at inlet is …
WebFinally, “Impulse” means that the fluid pressure drop (and consequent increase of velocity) takes place in the stator - i.e. in the nozzles. The fluid therefore passes through the rotor at an almost constant pressure, having only the velocity changed.
