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?
