13.12 Fluid A is found to have a surface tension of 0.080 N m−1, a density of 1.2 × 103 kg m−3 and a contact angle of 70° with dry glass. Fluid B is found to have a surface tension of 0.100 N m−1, a density of 3.1 × 103 kg m−3 and a contact angle of 110° with dry glass. A glass capillary tube with an inner radius 1 mm is lowered into a container of fluid A and an identical capillary tube is lowered into a flask of fluid B. To what height above (or below) the fluid surface will fluids A and B rise in their respective capillary tubes?
