Due to surface tension of water the component T cos @ acting all along the circumference of the capillary tube 2 pi r would get added as 2 pi r T cos@. Here @ is the angle of contact of water with the material of the tube ie glass.
Hence this uplifts the water to a height till its weight gets balanced by 2 pi r T cos@.
The capillary fringe
It is still called water. The phenomenon that it's demonstrating is called capillary action.
Capillary Action
Capillary action.
When water rises from the soil by the roots of the plant. The capillary effect is done in a lot of things. Example: When water is obsorbed by the paper up the toilet paper tube.
This is known as capillary action, where water molecules are able to defy gravity and move upward in thin tubes due to the combined forces of cohesion (water molecules sticking together) and adhesion (water molecules sticking to the tube surface). This process is important for plants in transporting water from the roots to the rest of the plant.
Liquid rises in and out of cappilarry to compansate pressure difference. Rise of a liquid in capillary is indirectly proportional to radius of tube so liquid goes higher in a narrow tube.
It draws narrow tubes inside plant stems to get the water.
The process is capillary action. The part is the xylem
Capillary motion is a movement of liquids in small tubes. This motion can be also ascensional.
Capillary action, which is the result of adhesive and cohesive forces between the water molecules and the tube surface, allows water to climb up narrow tubes against gravity. This phenomenon is due to the combination of surface tension and the adhesive forces between the water and the tube material.
Capillary tubes are renowned for their capillary action on liquids, i.e. they cause liquids to rise up inside them. Capillary tubes are the essence of thermometers that use a liquid indicator. In biology and the plant world, capillary tubes are fundamental to the movement of fluids through the systems of living organisms.
