The degree of reaction of hydraulic turbine is defined as the ratio of:
1
Change of Kinetic energy inside the runner per unit weight to change in total energy inside the runner per unit weight
2
Change of kinetic energy inside the stator per unit weight to change in total energy inside the runner per unit weight
3
Change of Pressure energy inside the runner per unit weight to change in total energy inside the runner per unit weight
4
Change of Pressure energy inside the stator per unit weight to change in total energy inside the runner per unit weight
