Difference Betwixt Francis Too Kaplan Turbine

 In this mechanical technology scientific discipline lecture nosotros acquire close what is difference betwixt Francis too Kaplan turbine inward hydraulic machine 

Francis turbine too kaplan turbine is hydraulic  turbine which converts hydraulic release energy into mechanical energy.  Francis  too kaplan turbine is Categorized of Reaction turbine. In both of turbine used kinetic release energy too pressure level release energy for generating mechanical energy. 

Francis turbine is one-time turbine than kaplan turbine thence inward kaplan turbine is varies modifications that is why both turbine are different.difference betwixt Francis too kaplan turbine explicate equally below

Flow on
Turbine 
Francis turbine is a
Inward radial flow
Reaction 
turbine. 
Kaplan turbine is a
parallel flow reaction
turbine.
 Sizesize of francis turbine is 
large Compared to
Kaplan turbine. 
Size of kaplan turbine is 
Smaller Compared to
Francis turbine. 
 Shaft
Adjusted 
Direction of Shaft may
be vertical Or horizontal. 
Direction Of shaft is
always Vertical Because 
this Turbine is Axial.
 Water
Required 
Francis turbine required
medium Water for running. 
Kaplan Turbine required 
less water For running 
Head Francis turbine is Medium
head turbine.
Kaplan turbine is a
Low caput turbine. 
 Head in
Meter
Francis turbine required 
24 to 180 1000 head.
Keplan turbine required 
Less than thirty 1000 head.
 

 

 Number
Of blades
Or blade
 number of Vanes or 
blades inward Francis 
turbine is half dozen to 24.
Number of Vanes or 
blades inward Kaplan 
turbine is iv to 8.
  Blade 
adjustable 
 Francis turbine rotor
blade tin move non adjusted. 
Keplan turbine rotor
blade is adjustable. 
 

 Specific 
Speed 
60 to 300 (Lower than
Kaplan Turbine)
300 to yard ( higher than
Francis turbine)
 Friction Friction losses is more
in Francis turbine. 
Friction losses is less
in keplan Turbine. 
 
 
 Efficiency efficiency of Francis 
turbine is Less than 
Kaplan turbine. 
Efficiency Of kaplan 
turbine is Higher than 
Francis turbine. 
 Suitable 
For
Francis turbine is 
not suitable for purpose load.
Kaplan turbine is most
efficient under part
Load.
 Mechanism Francis turbine has
Simple Mechanism. 
kaplan turbine has
Difficult Mechanism
