Orr F, Scriven L, Rivas A. Pendular rings between solids: meniscus properties and capillary force. J Fluid Mech. 1975;67:723–742. 18. SpletAs the meniscus is concave and nearly spherical, the pressure below the meniscus will be (p o – 2T/r) where r is the radius of the meniscus. This is the condition of unstable equilibrium because the pressure in the liquid at this level just outside the capillary is p o .

Model of the evaporating meniscus in a capillary tube

SpletWe all have seen a meniscus for a liquid in the capillary tube, while doing an experiment with a capillary tube in our labs. When we pour a liquid in a tube like container, the top surface of the liquid (that is open to air) obtains a bulge like … SpletThere are still many unanswered questions related to the problem of a capillary surface rising in a tube. One of the major questions is the evolution of the liquid meniscus shape.

What Is The Shape Of A Liquid Meniscus In A Capillary Tube?

Liquid Meniscus in Capillarity

SpletThis occurs with water and a glass tube. A convex meniscus occurs when the molecules have a stronger attraction to each other than to the container, as with mercury and glass. A flat meniscus occurs with water in some types of plastic tubes; tubes made out of material that water does not stick to. SpletMeasured of Viscosity— The usual method for measurement of viscosity involves the determine of who time required for a present volume of liquid to fluid through a capillary.

(B) the liquid level in a capillary tube ... short hairstyles for boys

"SpletThe 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 curve. If the meniscus is convex, take your measurement at the highest point of the curve. The short answer: Take your measurement from the center of the meniscus. " - The liquid meniscus in capillary tube
