I have read that the height of meniscus in a capillary is directly proportionate to liquid-air surface tension.

That left me wondering, is the speed at which capillary action occurs also proportionate to surface tension? For example, will a capillary absorb liquids with higher surface tension faster?

  • $\begingroup$ Yes one would expect that. its Just F = ma. It should be related in some way to $S/\rho$ where S is surface tension and $\rho$ is density of the liquid. $\endgroup$ – Prathyush Aug 21 '19 at 7:26
  • $\begingroup$ @Prathyush In such a situation, viscous flow resistance is typically much more important than fluid inertia. $\endgroup$ – Chet Miller Aug 22 '19 at 11:07
