WebThe Young-Laplace equation is the expression that relates the pressure difference, AP, to the curvature of the surface and the surface tension of the liquid. It was derived independently by T. Young and P. S. Laplace around 1805 and relates the surface tension to the curvature of any shape in capillary phenomena.
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.
