Webone of the walls has a contact angle significantly greater than 90°. The height of the capillary rise depends on the spacing between the walls and also on the difference in contact angles at the two surfaces. When the contact angle at one wall is greater than 90° but the contact angle at the other wall is less than 90°, the meniscus can Web1.7 Capillarity. If a segment of a capillary tube is submerged in a liquid, the liquid in the capillary tube can rise or fall. This effect is called capillarity and is caused by the surface tension. The rise or fall depends on the relative magnitudes of the cohesion and the adhesion of the liquid to the walls of the capillary tube. WebSep 12, 2013 · The capillary dimensions are varied from 150 µm to 450 µm to study the effect of dimensions and the contact angle on the burst frequency.
