Differences between impulse and reaction turbine
IMPLUSE TURBINE | REACTION TURBINE |
---|---|
The potential energy of water is completely converted to kinetic energy while striking. | The potential energy of water is partially converted to kinetic energy while striking. |
The pressure of jet striking is atmospheric. | The pressure of jet striking is less than atmospheric |
It is not connected directly with pipe. | It is connected directly with pipe. |
Ex: Pelton wheel turbine | Ex: Francis Turbine |
Draft tube is not required. | Draft tube is required in tailrace. |
