Capillary action speed formula?

  1. Nov 18, 2015 #1
    Hi,

    I was looking for a formula to describe capillary action speed in a medium.

    On wikipedia (https://en.wikipedia.org/wiki/Capillary_action) I came across a formula which describes the cumulative volume of a liquid drawn by capillary action after time t

    where V is cumulative volume, A is area, S is sorptivity and t is time.

    If I reverse this to

    t = (V/AS)2, is this the speed/time correlation I'm looking for, or is it just a relation with volume?


    Thank you

    Allison
