Abstract
Accurate measurements of surface tension of liquid metals having low capillary constants (the ratio between density (ρ) and surface tension (σ), ρ/σ) have been attempted using the constrained drop method. High accuracy of surface tension measurements was obtained by making a large axi-symmetric liquid drop and adopting a developed image capturing system composed of a high-resolution charge-coupled device (CCD) camera, an additional CCD camera to adjust the level of the metal drop and a He-Ne laser.
