Thus, if one measures a pressure potential value of -15 kPa in a given soil, then the tension of that soil is 15 kPa. There is a clear relationship between soil water tension and water content, which can be illustrated with a soil-water retention curve, or soil-water characteristic curve.

Web8 Apr 2015 · The forces responsible for retention of water in the soil after the drainage has stopped are due to surface tension and surface attraction and are called surface moisture tension. This refers to the energy … Webis divided by the depth of soil (50 mm) then multiplied by 100%. to calculate the Volumetric Water Content of 20% (= 10 mm / 50 mm * 100%) An important note. While the soil moisture content (20%) is the same as Example No. 2, the equivalent depth of water is only 10 mm (compared to 20 mm in Example No. 2).
WebSurface tension Molecules at fluid interface are exposed to different forces than within fluids. For example, at the water-air interface, a net inward force exists because of higher … WebAt that moment the moisture content is determined. From figure 22 it is clear that within the range of 10% to 75% R.H. the relation is almost linear and very steep which shows that a change in R.H. has only a relative small effect on the pF-value (range of pF = 5,5 till pF = 6,5).
WebSurface tension is a cohesive force resulting from attraction between molecules in the liquid. A drop of water on the waxed slide stands higher because the adhesive force between water and wax modifies its angle of contact. The water does not wet the wax. A little wetting agent added to the water reduces its surface tension and the drop ...
