The Laplace pressure is the pressure difference between the inside and the outside of a curved surface that forms the boundary between two fluid regions. [1] The pressure difference is caused by the surface tension of the interface between liquid and gas, or between two immiscible liquids. The Laplace pressure is determined from the Young ...
In physics, the Young–Laplace equation (/ l ə ˈ p l ɑː s /) is an algebraic equation that describes the capillary pressure difference sustained across the interface between two static fluids, such as water and air, due to the phenomenon of surface tension or wall tension, although use of the latter is only applicable if assuming that the wall is very thin.
Δp is the pressure difference, known as the Laplace pressure. [12] γ is surface tension. R x and R y are radii of curvature in each of the axes that are parallel to the surface. The quantity in parentheses on the right hand side is in fact (twice) the mean curvature of the surface (depending on normalisation).
Laplace's law or The law of Laplace may refer to several concepts, Biot–Savart law, in electromagnetics, it describes the magnetic field set up by a steady current density. Young–Laplace equation, describing pressure difference over an interface in fluid mechanics. Rule of succession, a smoothing technique accounting for unseen data.
The vapour pressure above the curved interface is then higher than that for the planar interface. This picture provides a simple conceptual basis for the Kelvin equation. The change in vapor pressure can be attributed to changes in the Laplace pressure. When the Laplace pressure rises in a droplet, the droplet tends to evaporate more easily.
“It’s so rich,” Canal says in the video. “Like Tom Cruise.” The pastry is so famous, it was immortalized in HBO comedy series “Hacks.”In the Season 3 premiere, fictional superstar ...
The characteristic height is the distance from the bottom of the meniscus to the base, and exists when the Laplace pressure and the pressure due to gravity are balanced. One can reorganize to show the capillary length as a function of surface tension and gravity.
