A capillary tube of radius 0.5 mm is dipped vertically in a liquid of surface tension `0.04 N/m` and relative density `0.8 g/cc`. Calcukate the height of capillary rise , if the angle of contact is `10^@`.

When a capillary tube of radius 'r' is dipped vertically in a liquid of surface tension T, the liquid rises to a height 'h' in the tube above the level outside the tube. If the angle of contact is theta , the density of the liquid is rho , then the pressure difference is.

A capillary tube 0.14mm in diameter has its lower end immersed in a liquid of surface tension 0.054 N//m . If the density of a liquid is 860 kg//m^3 , find the height to which the liquid rises in the tube.(Angle of contract of liquid with glass is 28^@ and g=9.8 m//s^2 ).

A film is held on a ring of area 0.05m^2 of liquid of surface tension 0.05 N/m, then the surface energy is

When glass capillary tube of radius 0.4 mm is dipped into mercury, the level inside the capillary stands 1.24 cm lower than that outside. Calculate the surface tension of mercury. (Angle of contact of mercury with glass = 135^@ , g = 9.8 m//s^2 , density of mercury = 13.6 xx 10^3 kg//m^3 )

A long capillary tube of radius 0.2 mm is placed vertically inside a beaker of water. If the surface tension of water is 7.2xx10^(-2)N//m the angle of contact between glass and water is zero, then determine the height of the water column in the tube.

Calculate the density of paraffin oil, if glass capillary of diameter 0.25 mm dipped in paraffin oil of the surface tension 0.0245 N//m rises a height of 4 cm. (angle of contact of paraffin oil with glass is 28^@ and g=9.8m//s^2 )

A capillary tube of radius r is lowered into water whose surface tension is alpha and density d . The liquid rises to a height. Assume that the contact angle is zero. Choose the correct statement (s):

A capillary tube of radius r is dipped in a liquid of density rho and surface tension S. if the angle of contanct is theta , the pressure difference between the two surface in the beaker and the capillary ?

A capillary tube of radius 0.02 cm is dipped vertically in a beaker containing mercury. The level of mercury in the tube with respect to the mercury level in the beaker will be (Given density of mercury 13.5 g//cc, Surface tension 540 dyne/cm and the angle of contact 135^@ )

A capillary tube of radius r can support a liquid of weight 6.28 xx 10^-4 N . If the surface tension of liquid is 5 xx 10^-2 N//m , the radius of the capillary tube will be.........
