WebSep 7, 2010 · Capillary action is the physical phenomenon arising due to surface tension on the interface of immiscible media. Commonly, capillary phenomena occur in liquid media and are brought about by the curvature of their surface that is adjacent to another liquid, gas, or its own vapor. WebCAPILLARY ACTION The tendency of a fluid to be raised or suppressed in a narrow tube, or capillary tube, is called capillary action. If a capillary tube is placed vertically into a liquid, as shown in Figure 8, capillary action will raise or suppress the liquid inside the tube depending on the combination of substances. WebMay 24, 2015 · (The minus sign indicates that the meniscus would be lower inside the tube than outside.) So the meniscus rises or falls about 25x as much with glass tubing compared with plastic. A 40/25=1.6mm diameter PTFE tube would be required to lower the meniscus by 0.7mm. Share Cite Improve this answer Follow answered Sep 9, 2016 at 22:00 … inwall s\\u0026c
