Calculate the diameter of a capillary tube in which mercury is derpessed by 1.21 cm. Given surface tension for mercury is `540 xx 10^(-3) "Nm"^(-1).` the angle of contact with glass is `140^(@)` and density of mercury is `13.6 xx 10^(3) "kg" m^(-3).`

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 tube of mercury barometer is 4mm in diameter. How much error does the surface tension cause in the reading? Surface tension of mercury = 540" cc "10^(-3) Nm^(-1) , angle of contact = 135^(@) . Density of mercury = 13.6 xx 10^(33)kg m^(-3) .

Density of mercury is 13.6 g cm^(-3) . Its density in kg m^(-3) is

Calculate the height to which water will rise in a capillary tube of diameter 1xx10^(-3) m [given surface tension of water is 0.072Nm^(-1) angle of contact is 0^(@),g=9.8ms^(-2) and density of water =1000kgm^(-3) ]

Water rises in a capillary tube to a height of 10 cm . If surface tension of water is 9.8 xx 10^(-2) "Nm"^(-1) . Then find out the radius of the capillary tube. Given g=9.8 "ms"^(-2) and density of water = 10^(3) "kgm"^(-3).

What is the excess pressure inside a drop of mercury of radius 3.0 mm? (Surface tension of mercury is 4.65 xx 10^(-1) N m^(-1) )

Find the difference in levels of mercury in the limbs of a U-tube if the diameter fo bore of one limb is 1mm and of the other 4mm. The surface tension of mercury is 544 xx 10^(-3) "Nm"^(-1) its density is 13.6 xx 10^(3) "kg" m^(-3) and angle of contact is 130^(@).

Calculate the ratio of surface tension of mercury and water if in a capillary tube, mercury is depressed by 3.45 cm and water rises by 9.8 cm in the same tube. The angle of contact for mercury is 140^@ and that for water is 0^@.

The diameter of the mercury barometer tube is recorded as 6 mm. How much error is introduced due to surface tension in this reading. Surface tension of mercury is 540 xx 10^(-3)" N/m" Angle of contact for mercury is 140^@ .
