Derivation of formula for capillary action

  1. Feb 23, 2012 #1
    the height upto which liquid rises in capillary tube is 2S cosθ / ρgR
    I need a derivation for this - please
    I know that a combination of adhesive force , surface tension and weight creates the contact angle θ but how to proceed after that?
    To calculate height h i need to know the force by which tube is pulling the liquid(adhesive force) but how can i know that?

    Its really important for me to know the derivation so plz help me

    hope this helps.. too lazy to type the whole thing.. also read articles on wikipedia baout surface tension and capillary action.. you should be able to figure out..
