The height of liquid in a tube due to capillarity can be calculated. h = 2 σ cosθ / (ρ g r) (1) where. h = …
Jurin's law, or capillary rise, is the simplest analysis of capillary action—the induced motion of liquids in small channels —and states that the maximum height of a liquid in a capillary tube is inversely proportional to the tube's diameter. Capillary 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 discovere… WebApr 7, 2024 · Capillary rise ( h) = 2 T c o s θ r ρ g Which for an angle of contact of 0° becomes:- Capillary rise ( h) = 2 T r ρ g Occurrence of Capillary Action Capillary …
