Shape of liquid meniscus
WebbThe model developed can be used for accurate prediction of three-dimensional meniscus shape on structured surfaces with micro/nano-scale features, which is necessary for … Webb20 juni 2024 · tan α = positive ∴ α is acute angle i.e., the resultant force directed outside the liquid. Hence the liquid meniscus must be concave upward. Example : Water in glass capillary tube. F c > √2F a . tan α = negative ∴ α is obtuse angle i.e., the resultant force directed inside the liquid. Hence the liquid meniscus must be convex upward.

WebbIt forms a shape that looks something like that. And so the first thing we might ask is what'll we call this thing. And this right over here is called a meniscus. Meniscus. And in particular this meniscus, because the fluid is higher near the container than it is when you're away from the container, we would call this a concave, concave meniscus. WebbFor a sufficiently narrow tube with circular cross-section, the shape of the meniscus will approximate a section of a spherical surface, while for a large container, most of the upper surface of the liquid will be almost flat, only curving up (if concave) or down (if convex) …
