What are the advantages of Impulse and Reaction turbine?

Impulse turbines are advantageous due to their simplicity and efficiency at high speeds, as they utilize the kinetic energy of water jets to turn the rotor. They can operate effectively across a range of flow conditions and are less sensitive to variations in water head. Reaction turbines, on the other hand, generate power through both pressure and velocity changes, making them highly efficient in low-head applications. Their design allows for smoother operation and higher efficiency in converting hydraulic energy into mechanical energy.
