Applying Young-Laplace equation on meniscus formed due to rise of liquid on a single plate
Let's say we have a single plate with liquid on both sides rising up due to surface tension. The meniscus formed has a radius of curvature
I'm trying to find the excess pressure, i.e, the pressure difference between the exterior and interior of the meniscus.
Since there is only one curved surface (the meniscus which extends across the length of the plate) whose radius of curvature is
where
However, I know that the excess pressure should be
The only way we get the factor of
Here's an image which shows what kind of a setup I'm referring to (credits: Vincent Émyde)
