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 … WebbThe % slurry can now be determined by the volume of drained resin remaining in the syringe minus the volume occupied by the frit (~ 0.25 mL). The % slurry is calculated using the equation: 100 × (volume of drained resin - volume of frit)/10. WebbA slurry is generally more viscous than a base liquid and behaves as a non-Newtonian fluid. Some equations to estimate the heat transfer characteristics have been pro- posed for the slurry, but most require physical properties that are difficult to know. This is why we employed the correlation based on the apparent viscosity in this study. portpatrick to newton stewart
