An open capillary tube is lowered in vessel with mercury. The difference between the levels of the mecury in the vessel and in the capillary tube `/_\h=4.6 mm`. What is the radius of curvature of the mercury meniscus in the capillary tube? Surface tension of mercury is `0.46N//m`, density of mercury is `13.6gm//"cc"`.

The meniscus of mercury in the capillary tube is

What is the shape of a liquid meniscus in a capillary tube dipped in mercury?

The factor responsible for lower mercury level in a capillary tube is

If water rises in a capillary tube upto 3 cm . What is the diameter of capillary tube (Surface tension of water = 7.2 xx 10^(-2) N//m )

The excess pressure inside mercury drop of diameter 4 mm is (Take surface tension of mercury is 0.465 N/m)

Calculate the diameter of a capillary tube if angle of contact of mercury is 140^@ and mercury is depressed by 10.2 mm in the tube. Surface tension of mercury is 5400 xx 10^(-4)" N/m" .

The lower end of a capillary tube is immersed in mercury. The level of mercury in the tube is found to be 2 cm below the outer level. If the same tube is immersed in water, up to what height will the water rise in the capillary ?

When a capillary tube is immersed vertically in mercury, the level of mercury in the capillary is observed to be depressed. This is due to –

Find the depression of the miniscus in the capillary tube of diametre 0.4mm dipped in a beaker containning mercury (density of mercury =13.6xx10^(3)kg//m^(3) and surface tension of the mercury is 0.49 N//m and angle of contact is 135^(@) ).

The lower end of a capillary tube of radius 1 mm is dipped vertically into mercury. (a) Find the depression of mercury column in the capillary. (b) If the length dipped inside is half the answer of part (a), find the angle made by the mercury surface at the end of the capillary with the vertical. Surface tension of mercury =0.465Nm^-1 and the contact angle of mercury with glass =135^@ .
