An air bubble of radius 0.2 mm is situated just below the water surface. Calculate the guage pressure. Surface tension of water = 7.2 xx 10^(-2) N/m`.

An air bubble of radius 0.2 mm is situated just below the water surface. Calculate the gauge pressure. Surface tension of water = 7.2 xx 10^-2 N//m .

An air bubble of radius 0.1 mm is ready to leave the surface of taken. Then the pressure inside in Nm^-2 is (Surface tension of water: 70xx10^-3 N//m , 1 atm = 1xx10^5 N//m^2)

If a small air bubble of radius 0.1 mm is formed just below the surface of water, then the pressure inside the air bubble will be (P=10^5N//m^2,T=0.07 N//m)

A long capillary tube of radius 0.2 mm is placed vertically inside a beaker of water. If the surface tension of water is 7.2xx10^(-2)N//m the angle of contact between glass and water is zero, then determine the height of the water column in the tube.

A small air bubble of radius 0.1mm is situated at a depth of 20 m below the free surface of water . The external pressure on the bubble will be (Atm. Pressure = 10^5N//m^2,g=10m//s^2)
