The lower end of a capillary tube of diameter 2.0 mm is dipped 8.00cm below the surface of water in a beaker. What is the pressure required in the tube in order to blow a hemispherical bubble at its end in water? The surface tension of water at temperature of the experiments is `7.30 xx 10^(-2) Nm^(-1)`. 1 atmospheric pressure =` 1.01 xx 10^(5) Pa`, density of water `= 1000 kg//m^(3), g=9.80 ms^(-2)`. also calculate the excess pressure.

A narrow capillary tube is dipped 10 cm below water surface and a liquid bubble of radius 2 mm formed at the lower end by blowing air through the tube. a. Calculate the excess pressure due to surface tension. b. What is the pressure required in the tube in order to blow a hemispherical bubble at its end in water? The surface tension of water at temperature of the experiment is 7.30xx10^(-2) N//m . 1 atmospheric pressure = 10^(5) Pa , density of water = 1000 kg//m^(3)

The surface tension for pure water in a capillary tube experiment is

If the lower end of a capillary tube of radius 2.5 mm is dipped 8 cm below the surface of water in a beaker, then calculate the pressure within a bubble blown at its end in water, in excess of atompheric pressure. [Surface tension of water 72 xx 10^(-3) N/m]

What should be the pressure inside a small air bubble of 0.1 mm radius situated just below the water surface? Surface tension of water is 7.2 xx 10^(-2) Nm^(-1) and atmospheric pressure is 1.013 xx 10^(5) Nm^(-2) .

When one end of a capillary tube is dipped vertically in water, the pressure below the meniscus of water is
