The lower end of a capillary tube of diameter 2.00mm 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 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.
