WebApr 1, 2011 · The objective of this study was to develop an empirical equation for estimating the capillary rise in the saline-sodic soil area of Songnen Plain in China based on the Averianov formula. The capillary rise was observed under five controlled groundwater levels by lysimeters. Field experiment results indicated that capillary rise had close … WebCapillary = capillary water is water that can rise upwards in the soil within the fine pores through binding of the water molecules in the pores, adhesion, but also through attraction between water molecules, cohesion. Silty soils have high capillarity and combine a large height of capillary rise with a high rate of capillary rise.

WebJun 10, 2024 · The capillary rise method is a test conducted to determine the surface tension of a liquid or the contact angle of liquid with soil or pipe material. Capillary rise is the rise in a liquid above zero pressure level caused by net upward force that is produced by the attraction of water molecules to a solid surface. WebCapillary Rise Capillary rise is one of the most well-known and vivid illustrations of capillarity. It is exploited in a number of biological processes, including drinking strategies of insects, birds and bats and plays an important role in a number of geophysical settings, including flow in porous media such as soil or sand.
