SURFACE-TENSION AND VISCOSITY OF LIQUID-METALS

In this paper, a simple relation between surface tension, gamma, and viscosity, eta, of a pure liquid, which can be derived from statistical mechanics, is reported: gamma/eta = 15/16(kT/m)1/2, where T is the temperature and m is the atomic mass. This has been checked by compiling published data for some liquid metals and agreement better than 20% is found over a general temperature range of DELTAT almost-equal-to 300 K around the melting point.
