Example: Capillary Rise in Water and Mercury ... The tube containing water exhibits positive capillary rise, where the water adheres to the sides of the tube causing the fluid to rise slightly. The tube containing mercury exhibits negative capillary rise. The fluid is drawn away from the walls of the tube, causing the fluid...

Capillary rise is the rise in a liquid above the level of zero pressure due to a net upward force produced by the attraction of the water molecules to a solid surface (e.g., soil or glass).

When free water is introduced to a capillary tube of clean glass, the water is observed to rise. Once equilibrium is reached (almost instantly), we can assume forces are at equilibrium and calculate the various forces at work. This derivation follows that of Jury et al., 1991. ... For a capillary rise of height H.

It also proposes a theoretical model of capillary rise using the hydraulic characteristics of growing media to predict the suitability of various substrates.

To calculate the capillary rise, the unsaturated hydraulic conductivity, K(q), needs to be known. The hydraulic conductivity is a function of the moisture content and the moisture content is a function of the pressure head.

The surface tension is determined by measuring the height of the capillary rise in a capillary tube. The capillary tubing used is inexpensive, but its diameter is not known. The first part of the experiment involves measuring the capillary rise for several different solvents.
