WebThe capillary number is a dimensionless quantity that relates the viscous forces in a system to the surface tension forces. It is defined as (Eq. 9.22) The capillary number is used whenever the forces resulting from fluid motion are to be compared to the forces resulting from surface tension. WebNov 1, 2024 · While most studies have investigated the role of capillary forces on particles at single interfaces, few have investigated the behavior of particles in thin films, where the particle size is comparable to the film thickness and may adsorb simultaneously at both interfaces. Such cases are especially important in understanding the role of ...

What Is Capillary Action? Definition and Examples

Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of, or even in opposition to, any external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a … See more Capillary comes from the Latin word capillaris, meaning "of or resembling hair." The meaning stems from the tiny, hairlike diameter of a capillary. While capillary is usually used as a noun, the word also is used as an … See more Capillary penetration in porous media shares its dynamic mechanism with flow in hollow tubes, as both processes are resisted by viscous forces. Consequently, a common apparatus used to demonstrate the phenomenon is the capillary tube. When the lower … See more When a dry porous medium is brought into contact with a liquid, it will absorb the liquid at a rate which decreases over time. When considering … See more • Bond number – Dimensionless number in fluid dynamics • Bound water – Thin layer of water surrounding mineral surfaces. • Capillary fringe – Subsurface layer in which groundwater seeps up from a water table by capillary action See more The first recorded observation of capillary action was by Leonardo da Vinci. A former student of Galileo, Niccolò Aggiunti, was said to have investigated capillary action. In 1660, capillary action was still a novelty to the Irish chemist Robert Boyle, when he reported that "some … See more In the built environment, evaporation limited capillary penetration is responsible for the phenomenon of rising damp in concrete and masonry, while in industry and diagnostic … See more Capillary rise of liquid in a capillary The height h of a liquid column is given by Jurin's law $${\displaystyle h={{2\gamma \cos {\theta }} \over {\rho gr}},}$$ See more WebNov 12, 2024 · This capillary action experiment will amaze kids from toddlers, preschoolers, and kindergarteners to grade 1, grade 2, and grade 3 students.
