To know the difference between the inward flow and outward flow reaction hydro turbines we will compare them on the following points 

1. Energy of water 

2. Centrifugal head imparted 

3. Discharge 

4. Discharge 

5. Wheel tendency to race 

6. Suitability 

7. Application

Difference between inward flow and outward flow reaction hydro turbine 


Energy of water

In Inward flow reaction hydro turbine water enters at the outer periphery, flows inward and toward the center of the turbine, and discharges at the outer periphery whereas in outward flow reaction hydro turbine water enters at the inner periphery flows outward, and discharges at the outer periphery 

Centrifugal head imparted

In the Inward flow reaction hydro turbine negative centrifugal head reduces the relative velocity of water at the outlet whereas in the outward flow reaction hydro turbine positive Centrifugal head increases the relative velocity of water at the outlet.

Discharge

In an Inward flow reaction hydro turbine, the discharge does not speed up at exit whereas, in an outward flow reaction hydro turbine, the discharges do speed up at the Hostetler.

Speed control

In inward flow reaction hydro turbine it's easy to control the speed of the turbine effectively whereas, in an outward flow reaction hydro turbine, it's very difficult to control the turbine its speed.

The tendency of the wheel to race

an In inward flow reaction hydro turbine there is no tendency for the wheel to race with increasing speed whereas an in an outward flow reaction hydro turbine if the speed increase wheel tended hit.

Suitability

The inward flow reaction hydro turbine is quite suitable for medium to high speed and is best suitable for large output power producing units whereas the outward flow reaction hydro turbine is quite suitable for low or medium heads and small power production plants.

Application

The inward flow reaction hydro turbines are used for power production projects whereas the outward flow reaction hydro turbines are practically obsolete
