Shape of liquid meniscus
Did you know?
WebbThe shape of the liquid surface is curved near the place of contact with the solid. This curvature is called meniscus. The meniscus is formed at the surface of the liquid near the walls of a glass beaker. This because whenever a liquid is poured into a glass, two types of forces will act on that. The two forces are: Cohesive force and WebbThe level depends on the shape of the meniscus, or crescent. The meniscus is the curve seen at the top of a liquid in response to its container. The meniscus can be either …

WebbΔ P h = ρ g h. whereas the capillary pressure is. Δ P c = 2 γ R = 2 γ cos θ r. So balancing these we get our 'famous' equation: h = 2 γ cos θ ρ g r. Now we have a situation in which the height of our tube above the liquid, h m a x is smaller than h. For an equilibrium situation we still need the hydrostatic pressure and the capillary ...
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) …
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. the o\u0027donnell groupWebbA meniscus can go up or down. It all depends on if the molecules of the liquid are more attracted to the outside material or to themselves. A concave meniscus, which is what … the o\u0027connor law firm p.cWebbMeniscus shape.
