What is Basic Difference between Reaction turbine & Impulse Turbine?
Impulse Turbine: Power is developed due to only kinetic energy change. No change in pressure across blade. Partial admission of fluid. Profile type blade.Need of governing. Reaction Turbine: Power is developed due to pressure as well as kinetic energy change. Full admission of fluid. Airfoil type blade. Pure Impulse & reaction are not practical turbine. In a practical turbine mixture of both is used.
