[Solved & can be closed] How to determine the average properties of a mixture
Thread Content
This post was last edited by Lin Xuefeng on 2013-7-5 at 16:02. What formulas should be used to calculate the average viscosity and thermal conductivity of mixtures, and where can these formulas be found? I hope fellow users can help; I’m waiting for assistance online.
I usually use ASPEN Plus or SINET to determine the physical properties of mixtures; manual calculations are rather cumbersome and yield slightly less accurate results. If the original poster doesn’t have Aspen, they can send me the specific parameters and I’ll help calculate it.
Could you provide empirical formulas for the viscosity and thermal conductivity of mixtures at atmospheric pressure? I used them before, but have forgotten where I found them; thanks in advance. As for process simulation software, I haven’t used it much; I mainly do calculations by hand. I plan to start using it in the near future.
I’ve encountered this problem recently as well
