A clean tube of diameter 2.5 mm is immersed in a
liquid with a coefficient of surface tension = 0.4
N/m. The angle of contact of the liquid with the
glass can be assumed to be 135°.
The density of the liquid = 13600 kg/m3.
What would be the level of the liquid in the tube
relative to the free surface of the liquid inside the
tube.
