WebCapillary action is one of the most common fluid mechanical effects explored in the field of microfluidics. Jurin's law is named after James Jurin , who discovered it between 1718 … Capillary action is observed in thin layer chromatography, in which a solvent moves vertically up a plate via capillary action. In this case the pores are gaps between very small particles. Capillary action draws ink to the tips of fountain pen nibs from a reservoir or cartridge inside the pen. See more 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 … 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 Capillary rise of liquid in a capillary The height h of a liquid column is given by Jurin's law See more Capillary comes from the Latin word capillaris, meaning "of or resembling hair."
