Shape of liquid meniscus
WebbIn the Cartesian system of coordinates ( X, Y, Z ), the meniscus profile Z = H ( X, Y) describes the liquid elevation above the reference plane ( X, Y ), which coincides with the horizontal liquid level far away from the fibre. The centre of coordinates is … 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 …
Shape of liquid meniscus
Did you know?
WebbWhen 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. Capillary Action Capillary action is the rise of a liquid that … WebbThe long answer: To read a meniscus, you first need to see what type of meniscus your liquid forms. If the meniscus is a concave meniscus, read at the lowest level of the …
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 … 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.
WebbThe upper surface of a liquid in a tube is called the meniscus, and the shape of the meniscus depends on the relative strengths of the cohesive and adhesive forces. In …
Webb24 feb. 2024 · For 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 molecules and the solid surface are stronger than the cohesive forces between the liquid molecules. how can i use the f keysWebb8 juni 2024 · Shape of liquid meniscus affected by polarity switch after stable emission (EMI-BF 4, V 0 = 2400 V, Q = 1.15 × 10 −11 m 3 s −1).
