The liquid meniscus in capillary tube

SpletThe liquids of known densities are allowed to flow through the capillary maintaining the same differences of levels in the limbs and the time equation which governs the flow lead to the relation: 3/16 Where and are viscosity coefficients of the liquid and water, respectively and dl and d2 are the densities of liquid and water, respectively. SpletCAPILLARY ACTION •ube having a A t very fine bore ( 1mm) and open at both ends is called a capillary tube. • If one end of a capillary tube is dipped in a liquid which partially or completely wets the surface of the capillary (like water in glass) the level of liquid in the capillary rises. • On the other hand, if the capillary tube is ...

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. Many capillary-tube viscosimeters have been arranged, but Ostwald and Ubbelohde viscosimeters will among to most frequently used.

Spleti. The meniscus forms an angle θ, the contact angle, with the inner wall of a capillary tube with circular cross section. The contact angle is determined by the abil-ity of the liquid to wet the inner surface of the tube. ii. For narrow tubes the shape of the meniscus is assumed to be spherical with radius R. The contact angle is then SpletOne striking feature leading to the outstanding efficiency of nanofluids in enhanced oil recovery is the structure of nanoparticles, which induces oscillatory structural forces in the confined space between fluid–fluid interfaces or air–liquid and liquid–solid interfaces. 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. city of chicago human resources number

SpletMenisci are a manifestation of capillary action, by which either surface adhesion pulls a liquid up to form a concave meniscus, or internal cohesion pulls the liquid down to form a convex meniscus. This phenomenon is important in transpirational pull in plants.
