Properties of Matter Part 3

Surface tension of two liquids (having same densities), T1 and T2, are measured using capillary rise method utilizing two tubes with inner radii of r1 and r2 where r1>r2. The measured liquid heights in these tubes are h1 and h2 respectively. [Ignore the weight of the liquid above the lowest point of miniscus]. The heights h1 and h2 and surface tensions T1 and T2 satisfy the relation:
