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]

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.

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 times 10^2 Nm^-1 .1 atmospheric pressure =1.01 times 10^5 Pa density of water =1000 kg//m^3,g=9.80 ms^-2 . Also calculate the excess pressure.
