The lower end of a capillary tube of diameter 2.00 mm is dipped 8 cm below the water surface in a beaker. what is the pressure required in the tube in order to blow a hemispherical bubble at its end in water? density of water= 10^3 kg/m^3
surface tension of water= 7.3×10^-2 N/m^2
atmospheric pressure= 1.01× 10^5 pa
surface tension of water= 7.3×10^-2 N/m^2
atmospheric pressure= 1.01× 10^5 pa
