Considering the availability and derivation of Roscoe's equation for absolute viscosity calcula- tion,the method to adopt λ_0 value,so-called λ_f,was proposed by experimentally deter- mining relational curve of the measured height,H,of metal melt vs logarithmic oscillation decrement,λ,extrapolating H into zero,if such corresponding λ value is taken.Experimental results show that the proposed method not only satisfies the availability of original equation but also eliminate the effects of:“end and slippage”,so as to improve the accuracy for liquid Cu and Sn examinations.
