Two liquids, (having surface tensions T1 and T2 and densities ρ1 and ρ2) are made to rise in (small radii) capillary tubes (of glass) of radii r1 and r2, respectively. Their, respective, angles of contact, with glass, are θ1 and θ2. The first liquid rises to a level h above the general outside level while the second liquid falls to a level h below the general outside level. We would then have
