A glass capillary tube sealed at the upper end has internal radius `r`. The tube is held vertical with its lower end touching the surface of water. Calculate the length `(L)` of such a tube for water in it to rise to a height `h (lt L)`. Atmospheric pressure is `P_(o)` and surface tension of water is T. Assume that water perfectly wets glass (Density of water = `rho`)

A narrow tube of length l and radius r is sealed at one end. Its open end is brought in contact with the surface of water while the tube is held vertical. The water rises to a height h in the tube. The contact angle of water with the tube wall is theta , density of water is rho and the atmospheric pressure is P_(o) . Find the surface tension of the liquid. Assume that the temperature of air inside the tube remains constant and the volume of the meniscus is negligible.

A glass capillary tube of radius r is placed vertically touching the surface of water. The water rises to height h in capillary tube. If now the tube is dipped into water till only h/2 length of it is outside the water surface the , radius of curvature of the meniscus of water in capillary tube will be,

A glass capillary tube of radius r is placed vertically touching the surface of water. The water rises to height h in capillary tube. If now the tube is dipped into water till only h/2 length of it is outside the water surface the , radius of curvature of the meniscus of water in capillary tube will be,

A glass capillary tube is held vertical and put into contact with the surface of water in a tank. It was observed that the liquid rises to the top of the tube before settling to an equilibrium height h_(0) in the tube. Assume that water perfectly wets glass and viscosity is small. Is the length of the capillary tube larger then 2h_(0) ?
