CAPILLARITY


DEFINATION OF CAPILLARITY :-

It is defined as the rise or fall in the level of liquid in a tube when it is immersed in a liquid compared with the adjacent general level of liquid.


CAPILLARY RISE :-

If the liquid rises in the tube then, it is called as "Capillary rise".

EXPRESSION FOR CAPILLARY RISE :-


          
          
      h=[4S]/[pgr]


Where,
     S=surface tension
       p=density of water
     r=radius of glass tube
     g=gravity


CAPILLARY FALL :-

If the liquid fall in tube then, it is called "Capillary fall".

EXPRESSION FOR CAPILLARY FALL :-


      h=[4S cos0]/pgr


     Where,
           S=surface tension
               p=density of water
           r=radius of glass tube
           g=gravity
