A U-tube is made up of two capillary tubes of bores 1 mm and 2 mm. The tube is held vertically and some part of it is filled with a liquid of surface tension 0.049N . m^-1 and of zero angle of contact. If the level difference of the liquid in the two arms is 1.25 cm, then determine the density of the liquid.

A capillary tube with a bore diameter of 0.5 mm is dipped upright in a liquid having surface tension 0.03 N. m^-1 . The specific gravity of the liquid is 0.8 and the liquid wets the surface of the tube completely. Up to what height will the liquid rise in the tube?
