How To Read a Meniscus of a Liquid - What is a 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 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 … Webb20 juni 2024 · tan α = positive ∴ α is acute angle i.e., the resultant force directed outside the liquid. Hence the liquid meniscus must be concave upward. Example : Water in glass capillary tube. F c > √2F a . tan α = negative ∴ α is obtuse angle i.e., the resultant force directed inside the liquid. Hence the liquid meniscus must be convex upward. meats for christmas lunch

"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. " - Shape of liquid meniscus

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 … 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.

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 … Webb12 apr. 2024 · Due to the COVID-19 pandemic, the global Liquid Lenses market size is estimated to be worth USD 32 million in 2024 and is forecast to a readjusted size of USD 45 million by 2028 with a CAGR of 4 ...

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.
