Webb1 sep. 2002 · The Thomas equation has been widely used almost by all researchers on ice-slurry. However, this equation overpredicts the viscosity of ice-slurry at C >15%, as was shown by Hansen [4]. Hansen used the Jeffrey's equation with the constant A =4.5 to get the best fit with experimental results. WebbAs Bill says, you cannot calculate the viscosity knowing % solids, SG/RD, etc! In some processes, like diamond rotary panning, the viscosity is critical. Depending on the specific VISCOSITY characteristics of the slurry, the same % solids, particle size distribution, RD will give you quite different viscosity. What is the application?
