Derivation of young laplace equation

WebYoung–Laplace equation In physics, the Young–Laplace equation is a nonlinear partial differential equation that describes the equilibrium pressure difference sustained across … WebIn the Young equation (equation 7) only γ LV and cos θ are directly measurable. However, γ SV and γ SL have been found to be useful parameters for predicting the adhesion between materials. Fox and Zisman 39 obtained an estimate of the surface free energy of a solid by plotting cos θ vs. γ LV for a homologous series of liquids on the surface.
