There are some basic differences between impulse and reaction turbines as mentioned in Table 5.1.
Table 5.1 Differences Between Impulse and Reaction Turbines
| Impulse Turbines | Reaction Turbines |
|---|---|
| Pressure drops occur only in nozzles.It has constant blade channel area.It has profile type blades.It can be used for small power development.It has lower efficiency due to high losses. | Pressure drops occur in moving blades as well as fixed blades.It has varying blade channel area.It has aerofoil blade cross-section.A considerable power developed is possible.It has higher efficiency than that of impulse turbines. |
