A capillary tube of radius 1 mm is immersed in a beaker of mercury. The mercury level inside the tube is found to be 0.536 cm below the level in the reservoir. Determine the angle of contact between the mercury and glass.

A capillary tube of radius 5 xx 10^-4 m is immersed in a beaker filled with mercury. The mercury level inside the tube is found to be 8 xx 10^-3 m below the level of reservoir. Determine the angle of contact between mercury and glass. Surface tension of mercury is 0.465 N//m and its density is 13.6 xx 10^3 kg//m^3 . (g= 9.8 m//s^2 )

The angle of contact between glass and mercury is

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^@ )

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 )

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 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^@ .

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.

If a capillary tube is dipped into a liquid and the levels of the liquid inside and outside are same then the angle of contact will be

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 ?
