Problem 2.167

A glass capillary of length $l=110 \mathrm{~mm}$ and inside diameter $d=20 \mu \mathrm{m}$ is submerged vertically into water. The upper end of the capillary is sealed. The outside pressure is standard. To what length $x$ has the capillary to be submorged to make the water levels inside and outside the capillary coincide?
