Difference between Impulse Turbine and Reaction Turbine:
The Difference between Impulse Turbine and Reaction Turbine is given below:
SL no | Impulse Turbine | Reaction Turbine |
1 | The total available energy of the water is converted into kinetic energy before it strikes the runner. | Only a part of the available energy is converted into kinetic energy. |
2 | The water flows through the nozzle and strikes the runner buckets. | The water is guided by the guide blades and flow over the moving lades. |
3 | The water strikes the runner buckets with kinetic energy. | The water glides over the runner blades with pressure energy. |
4 | The pressure of the flowing water after striking the buckets remains constant. | The pressure of water reduces gradually when it flows through the runner. |
5 | It is not necessary that the wheel should run full. There should be free access of air between the blades and wheel. | It is essential that the wheel should always run full i.e., it is kept full of water. |
6 | Water is admitted over a part of the circumference of the wheel. | Water is admitted over the entire circumference of the runner wheel. |
7 | Flow can be regulated without loss. | Flow cannot be regulated without loss. |
8 | Draft tube is not required. | Draft tube is required. |
