Shape of liquid meniscus
WebbAs this picture shows, a 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 … 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.

WebbAs mentioned earlier, the Bézier curve method can be applied not only to the meniscus formed in a cylindrical capillary but also to calculate many other meniscus shapes. As … WebbIf the surface has about the same affinity for the liquid as the liquid does for itself, then the liquid will form a hemispherical shape on it. If the surface has less affinity for the liquid …
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 ... WebbIn this paper, a simple geometry method is proposed to solve the force balance equation on the liquid meniscus. Based on a proper model for the macroscopic dynamic contact …

WebbIn general, the shape of the surface of a liquid can be complex. For a sufficiently narrow tube with circular cross-section, the shape of the meniscus will approximate a section of a spherical surface, while for a …

The effects of key parameters such as the vapor space thickness, wick thickness, and the supporting columns arrangement on the heat transfer performance of the UTVC are analyzed. inception dream levelsWebbPG Concept Video Surface Tension Shape of Liquid Meniscus in a Tube by Ashish Arora Students can watch all concept videos of class 11 Surface Tension for... income protection for mortgageWebbIf the angle (θ>90∘) is obtuse, the surface of the liquid meniscus is convex. In this case, F cohesive >F adhesive. This happens in the case of mercury, where the liquid in the capillary tube falls. If the angle of contact (θ= 90∘), the surface of liquid meniscus is flat. In this case, liquid will not rise or fall in the capillary tube. income protection for over 65WebbFor an obtuse angle of contact, which is greater than 90 degrees, the liquid meniscus will have a concave shape. This is because the adhesive forces between the liquid … income protection for tradiesWebbHere, a self-driven system of a smart liquid gating membrane is further developed by designing a new sytem based on a liquid gating magnetoelastic porous membrane with … income protection free cover limitWebbWhen liquid mercury is confined in a tube, its surface (meniscus) has a convex shape because the cohesive forces in liquid mercury tend to draw it into a drop.
