Capillary depression height

WebThe height of the capillary fringe at a site strongly depends on its subsurface geology. For pure water at 20°C in a clean glass tube, the height of capillary rise is approximately: where h t is the height of capillary rise in centimeters, and r is the radius of the capillary tube in centimeters. WebAug 3, 2024 · From the relation (1) we can see that with increasing radius of the capillary, the height of the liquid level in the capillary decreases.
