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 … 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

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. WebbT 1= Force due to surface tension at the liquid-solid interface. T 2= Force due to surface tension at the air-solid interface. T 3= Force due to surface tension at the air-liquid interface. For the equilibrium of the drop, T 2=T 1+T 3cosθ. cosθ= T 3T 2−T 1. bitwarden premium vs family
