Capillary depression height
WebSep 16, 2024 · The height to which the water rises depends on the diameter of the tube and the temperature of the water but not on the angle at which the tube enters the water. The smaller the diameter, the higher the liquid rises. Figure 11.3. 3: The Phenomenon of Capillary Action. WebEquations (3) and (4) are also valid for capillary depression h of a non-wetting liquid. In this case, the meniscus is convex and is obtuse. ... Height through which liquid rises in a capillary tube is inversely proportional to the diameter of the capillary tube.

WebIn the horizontal capillary tube, it can move the liquids over very large distances. But, the height of the liquid in the tube, that can be raised or suppressed depends upon its weight. Hence, the height of the liquid hcan be calculated by this formula. Hence, the capillary rise hdepends upon several factors. http://physicsexperiments.eu/2123/height-of-liquid-level-in-capillary-tube
