The following important points may be noted for reaction turbines:
a) In a reaction turbine, the water enters the wheel under pressure and flows over the varies.
b) The hydraulic efficiency of a reaction turbine is the ration of the work done on the wheel to the energy (or head of water) actually supplied to the turbine.
c) The overall efficiency of a reaction turbine is the ratio of the power produced by the turbine to the energy supplied by the turbine.
d) A Kaplan turbine is an axial flow reaction turbine. The number of blades are generally 4 to 8 in a Kaplan turbine runner.
e) A Francis turbine is an outward flow reaction turbine. The number of blades are generally 16 to 24 in a Francis turbine runner.
