If a 5.0 cm long capillary tube with 0.10 mm internal diameter open at both end is slightly dipped in water having surface tension 75 dyne ` cm ^( -1) ` Find radius of curvature of meniscus at top in mm.

If a 5 cm long capillary tube with 0.1 mm internal diameter, open at both ends, is slightly dipped in water having surface tension 75 dyn//cm , state whether: water will rise halfway in the capillary, (ii) water will rig up to the upper end of capillary, (iii) water will overflow out of the upper end of capillary. Explain your answer.

The meniscus of mercury in a capillary tube is 1.356 cm below plane surface outside it . If the density is 13.59 gm/cc and surface tension is 547 dyne /cm , then the radius of curvature of its meniscus is

A capillary tube of length 10 cm and diameter of the bore is 0.5 mm dipped inwater vertically with one fourth of its total length outside the water . The radius of curvature of the meniscus will be (T = 75 dyne/cm and g = 1000 cm//s^(2) )

A capillary tube of inner diameter 0.5 mm is dipped in a liquid of specific gravity 13.6 and having surface tension 545 dyn/cm(angle of contact 130^(@) ) . Find the depression or elevation in the tube .

A vertical vapillary with inside diameter 0.50 mm is submergeed into water so that the length of its part emerging outside the water surface is equal to 25 mm . Find the radius of curvature of the meniscus. Surface tension of water is 73xx10^(-3)N//m .

A tube of insufficient length is immersed in water (surface tension =0.7N//m ) with 1 cm of it Given, radius of tube =1mm .

The excess pressure inside a small air bubble of radius 0.05 mm in water of surface tension 70 dyne cm^(-1) (in pascal)

Calculate the amount of energy evolved when 8 droplets of water ("surface tension" =7 2 "dyne"" "cm^(-1)) of radius 0.5 mm each combine into one.

A capillary tube whose inside radius is 0.6 mm is dipped in water in a bucket of surface tension 75 dyn e cm^(-1) To what height is the water raised in the capillary tube above the level water in bucket ? What is the weight of water raised ?
