Formula for capillary rise
WebApr 5, 2024 · The rise in capillary tube formula is given by the following surface tension of water formula: T= r (r+h/3)ρg2cosθ Steps to Follow for Arranging the Apparatus: Place the movable height stand on the table and adjust its base horizontally by leveling the screws. WebHeight of Capillary Rise/Fall - (Measured in Meter) - The Height of Capillary Rise/Fall is the level to which the water rises or falls in a capillary tube. Surface Tension - (Measured in Newton per Meter) - Surface tension is a word that is linked to the liquid surface. It is a physical property of liquids, in which the molecules are drawn onto every side.
