[Engineer in making]

Hi, I'm Working on Dynamic Fluids homework that wants me to explain the relationship between The capillary

 

and water drops diameter when are on contact like in the picture shown. Now I know that the smaller the

 

diameter of the drop, the faster the capillary is able absorb the drop. Thus, the level water should be higher the

 

smaller the drop's diameter is. However, I don't really know how to prove this using fluids equations. Should I

 

use Bond Number to prove this or in terms of surface tension where (σπDc cos(θ) = ρgV) ?
