A liquid of density `700 kg//m^3` rises to a height of 12 mm in capillary tube of 2.7 mm diameter. If angle of contact is `30^@`, find the surface tension of liquid, (`g = 9.8 m//s^2`)

A liquid of density 850 kg//m^3 has an unknown surface tension . However , it is observed that if rises three times high in a capillary tube as compared to pure water . If the contact angles for both are same , then the surface tension of liquid is (Surface tension of water = 7.0xx10^(-2) N//m )

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 diameter 0.6 mm dipped vertically into water. It rises to height of 6 cm in capillary tube, find the surface tension of water. (Given: density of water = 1000 kg//m^3, g = 9.8 m//s^2 ).

A liquid of density 800 kg//m^3 flowing steadily in a tube of varying cross-section. If area of cross-section at A is 4 cm^2 and at B is 2 cm^2 , if speed of liquid at A is 10 cm//s , calculate:- the difference in pressure at A and B.

A liquid of density 800 kg//m^3 flowing steadily in a tube of varying cross-section. If area of cross-section at A is 4 cm^2 and at B is 2 cm^2 , if speed of liquid at A is 10 cm//s , calculate:- the rate of flow at B

The surface energy of soap liquid film on a ring of area 0.15m^2 is (Surface tension of liquid = 5 N//m)

The surface tension of water is 0.072 N/m. The height to which water will rise in a capillary tube of bore diameter 0.048 cm will be (Angle of contact of water is zero , acceleration due to gravity is 10 m//s^2 and density of water =1000 kg//m^3 ).

The rise of a liquid due to surface tension in a narrow capillary tube of diameter 'd' is 'h'. If the diameter is reduced to d//2 , the rise will be

A capillary tube of uniform bore is dipped vertically in water which rises by 6 cm in the tube. Find the radius of the capillary tube if the surface tension of water is 72 dyne/cm (g= 980 cm//s^2 ).

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 ).
