Derivation of young laplace equation
WebYoung-Laplace Equation for a Thin Film The standard Young-Laplace Equation looks as such: $$\Delta p = \frac{2 \gamma}{r}$$ Where r is the local radius of curvature of the surface, γ is the surface tension, and Δp is the change of pressure across the gas-liquid interface. However, this is not WebThe Young-Laplace equation is usually introduced when teaching surface phenomena at an elementary level (Young 1992). In this case, the surface phenomena are often …
