Question

I was wondering how they came to the conclusion that 2g/R=60? 3. An extensible tube was found to stretch to a radius of 10 x 10 3 m when the pressure inside was greater than the outside pressure by 60 N/m2. A student was given the problem of finding the conditions under which the end of the tube could be placed in a liquid and a hemispherical bubble of radius 1.0 x 10 m be blown into it. The student was surprised to find that it did not matter how far down into the fluid the tube was placed and that it could be done only for a particular value of the surface tension of the fluid. What is the surface tension?

Explanation / Answer

Since,

2g/R + rgh = Pressure inside--------- (1)

60 + rgh = Pressure inside -------------(2)

therefore 2g/R = 60 on subtracting (2) from (1)
