Definition

The relation giving the pressure jump Δp across a static curved fluid interface as the product of surface tension γ and the sum of the interface principal curvatures: Δp = γ (κ1 + κ2); it quantifies how interfacial curvature produces a normal pressure difference between the two adjoining fluid phases under continuum capillarity assumptions.
