WebJun 8, 2024 · Height of the liquid be h Surface Tension of Liquid be T Contact angle θ Weight of liquid inside capillary = Volume * Density * g = π r 2 h ρ g Which is the downward force, and the force that is balancing this is the force due to Surface tension. Now, Surface tension is defined as the Force acting on a line which is on the surface. WebWe can see in the equation that height of capillary rise is inversely proportional to the diameter of the tube. Smaller the diameter of the tube greater will be the height of the water column in the tube. In soils, generally, as the grain size decreases the size of the voids or pores also decreases. WebAug 3, 2024 · The distance h between the levels of a liquid inside and outside the capillary can be determined from relationship (1) h = 2 σ r ρ g, where σ značí povrchové napsignifies the surface tension of the liquid at given temperature, r is the capillary radius, ρ is the liquid density and g is the gravitational acceleration. end of probate process
