Laplace Pressure in Capillarity and Surface Forces in Liquids (Curved Surfaces) Formulas

The Laplace Pressure is the pressure difference between the inside and the outside of a curved surface that forms the boundary between a gas region and a liquid region. And is denoted by ΔP. Laplace Pressure is usually measured using the Pascal for Pressure. Note that the value of Laplace Pressure is always positive.
