Difference between Inward flow and outward flow reaction hydro turbine
Energy of water
Inward flow reaction hydro turbine water enter at the outer periphery, flow inward and toward the centre of the turbine and discharges at the outer periphery
out ward flow reaction hydro turbine water enter at the inner periphery flow out ward and discharge at the outer periphery
Centrifugal head imparted
Inward flow reaction hydro turbine negative centrifugal head reduce the relative velocity of water at the out let
out ward flow reaction hydro turbine positive Centrifugal head increase the relative velocity of water at the outlet
Discharge
Inward flow reaction hydro turbine the discharge does not increase
out ward flow reaction hydro turbine the discharge increase
Speed control
inward flow reaction hydro turbine easy and effective
out ward flow reaction hydro turbine very difficult
Tendency of the wheel to race
inward flow reaction hydro turbine nil
out ward flow reaction hydro turbine if speed increase wheel tends to race
Suitability
inward flow reaction hydro turbine quite suitable for medium high speed best suitable for large output and units
out ward flow reaction hydro turbine quite suitable for low or medium heads
Application
inward flow reaction hydro turbine for power projects
out ward flow reaction hydro turbine practically obsolete
