    In impulse turbine only kinetic energy but in reaction both kinetic and pressure energy.

    In impulse turbine change in K.E takes place. In reaction turbine change in pressure energy takes place.

    In impulse turbine the steam flows through the nozzle and strikes on the moving blades. ... But in the reaction turbine, the steam which glides over the moving blades possesses both pressure and kinetic energy. In impulse turbine the pressure of steam remains constant during its flow through the moving blades.

    In Impulse turbine there is conversion of Kinetic energy into mechanical engineerig but in Reaction turbine there is conversion of pressure energy to kinectic energy then into mechanical energy

    In impulse turbine all hydraulic energy is converted into kinetic energy by a nozzle and it is is the jet so produced which strikes the runner blades. In reaction turbine only some amount of the available energy is converted into kinetic energy before the fluid enters the runner.

    It converts 100% PRESSURE ENERGY INTO 100% KENETIC ENERGY BUT IN IMPLUSE IT IS NUT POSSIBLE

    in case of impulse the total energy of the water at the intrance of the turbine is kinetic energy...and in case of reaction water pusses both kinetic as well as pressure energy..... thank you!

    In simple words impulse turbines has a nozzle in which steam or water is made to hit the blades or buckets in high kinetic energy an example of this is Pelton turbine whereas in reaction turbine there are guide mechanisms which directs the flow of water or steam which rotates it an example of this is Francis or Kaplan turbines.

    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.

    Blades is main difference between these two

    In the impulse turbine first all pressure energy of water convert into the kinetic energy through a nozzle and generate a high speed jet of water. This water jet strikes the blade of turbine and rotates it. In the reaction turbine there is pressure change of water when it passes through the rotor of turbine
