The lower end of a capillary tube of dimeter 2 mm is dipped 8 cm below the surface of water in a beaker. What is the pressure required in the tube to blow a hemispherical bubble at its end in water? the surface tension of water is `7.3xx10^-2 Nm^-1` `rho_water = 10^3 kg m^-3` g=`9.8 ms^-2` 1 atmospheric pressure=`1.013xx10^5Nm^-2` Also calculate the pressure inside the bubble.
