Shape of liquid meniscus

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 ...

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.

WebbIf 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. WebbA meniscus is a curved surface of a liquid. Cohesive forces are the attractive forces existing between the molecules of the same substance. For example, the cohesive force …

Webb6 dec. 2013 · The surface tension force pulls the liquid tangential to the wall of the capillary. When a capillary is dipped in water, it starts rising up due to pulling force from the solid-vapor interface. If the capillary has insufficient length, as the water rises it accelerates till the end of the capillary.
