PHXI10:MECHANICAL PROPERTIES OF FLUIDS

361169 A glass capillary sealed at the upper end is of length \(0.11\;\,m\) and internal diameter \(2 \times {10^{ - 5}}\;m.\) The tube is immersed vertically into a liquid of surface tension \(5.06 \times {10^{ - 2}}\;N/m\). To what length the capillary has to be immeresed so that the liquid level inside and outside the capillary becomes the same.

361170 In a surface tension experiment with a capillary tube water rises upto \(0.1\;\,m\). If the same experiment is repeated in an artificial satellite, which is revolving around the earth; water will rise in the capillary tube upto a height of :

1 \(0.1\;\,m\)
2 \(0.2\;\,m\)
3 \(0.98\,\;m\)

361172 A uniform capillary tube of length \(l\) and inner radius \(r\) with its upper end sealed is submerged vertically into water. The outside pressure is \({P_0}\) and surface tension of water is \(T\). When water levels inside and outside capillary coincide, length of capillary submerged into water is \(\dfrac{2 l}{\left(2+\dfrac{P_{0} r}{c T}\right)}\). Find value of \(c\).
