Radius of tube (given liquid-air surface tension,density,height of liquid column, Capillary action)
Formula description
Capillary action, or capillarity, is the ability of a liquid to flow against gravity where liquid spontaneously rises in a narrow space such as a thin tube, or in porous materials such as paper or in some non-porous materials such as liquified carbon fibre.
