Shape of liquid meniscus
WebbΔ 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. Now we have a situation in which the height of our tube above the liquid, h m a x is smaller than h. For an equilibrium situation we still need the hydrostatic pressure and the capillary ...
