Derive an expression for capillary rise
WebCapillary Rise When one end of a small, wettable tube is immersed in a liquid, surface tension causes the liquid to rise into the tube, reaching an equilibrium as shown in Fig. P6-7. The tube radius is R and the rise measured to the bottom of the meniscus is H. ... Problems 269 (c) Derive the expression for H again using CV 2. (d) If the ... WebSep 28, 2024 · The rise or fall of a liquid in a narrow tube is called capillarity or capillary action. Practical application of capillarity: 1. Due to capillary action, oil rises in the cotton within an earthen lamp. Likewise, sap raises from the roots of a plant to its leaves and branches. 2. Absorption of ink by a blotting paper. 3.
