WebAug 1, 2014 · The transition zone II (Fig. 1) under equilibrium conditions is located between a two dimensional capillary meniscus (I) and a flat wetting film (II).A rectangular coordinate system, (x 1, x 2) is used, in which x 1 and x 2 are the lateral and normal coordinates, respectively.The width of the capillary, 2H, is assumed to be much larger than the … WebThe formula for capillary rise that most people know is easily derived through a pressure balance between the capillary pressure and the hydrostatic pressure. The hydrostatic pressure equals Δ P h = ρ g h whereas the capillary pressure is Δ P c = 2 γ R = 2 γ cos θ r So balancing these we get our 'famous' equation: h = 2 γ cos θ ρ g r
