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@.
It is our common observation that the liquid always rises in a capillary tube , the effect is referred to as the " CAPILLARY ACTION ".capillary action of liquid is also due to their surface tension. the surface area to volume ration of a capillary of small bore is much smaller than the container in which liquid is placed. Like viscosity , the surface tension of a liquid also decreases with the rise of temperature owing to the weakening of the inter molecular attractions .
The capillary fringe
Water can creep up thin tubes In
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.
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.
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 is called capillary action
It is still called water. The phenomenon that it's demonstrating is called capillary action.
It draws narrow tubes inside plant stems to get the water.
Usually called 'capillary attraction' or 'capillary action' it refers to the way very thin tubes can draw water up themselves without any external changes in pressure or without suction being applied.
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.
