Abstract
This work presents a simple formalism for Schmidt number and its temperature dependence for liquid lithium. It is explained that the temperature dependence of Schmidt number (Sc = η/ ρD) can be understood through dependence of topological-short-range-order (TSRO) parameter on temperature. Expression for Schmidt number has been deduced in terms of average potential energy US of superficial core, probability of diffusional displacement (P) and the TSRO parameter (x) . Calculations have been made for liquid lithium across a broad range of temperature i.e. melting to boiling point. Highest deviation between calculated and experimental values is 9.2%,but in general deviations are within + 4.7% over the entire range. It is significant that derived equation for Schmidt number yields values that are not only in good agreement with experimental values over the liquid phase regime, but also predicts the expected values in corresponding temperature limits for the ideal gaseous phase (x = 1, D is large, so Sc → 1) and ideal crystalline phase (as x → ∞, Sc → ∞).
