The lower end of a capillary tube of diameter 2.00 mm is dipped 10.00 cm below the surface of the water in a beaker. The pressure required in the tube in order to blow a hemispherical bubble at its end in water is? The surface tension of water at the temperature of the experiment is $7.3\times {10}^{-2} \mathrm{N}/\mathrm{m}$, atmospheric pressure = $1.01\times {10}^5 \mathrm{Pa}$, the density of water = 1000 $\mathrm{kg} {\mathrm{m}}^{-3}$, g = 10 $\mathrm{m} {\mathrm{s}}^{-2}$.
