Viscosity of a Slurry

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

The viscosity of a slurry, abbreviated \(\eta_s\), slurry being a mixture of liquids and solids, is comparitive to the viscosity of the liquid phase.

 

Viscosity of a Slurry formula

\(\large{ \eta_s = \frac {\mu} {\eta_r}  }\)   

Where:

 Units English Metric
\(\large{ \eta_s }\)  (Greek symbol mu) = viscosity of a slurry \(\large{\frac{lbf-sec}{ft^2}}\)   \(\large{Pa-s}\)
\(\large{ \mu }\)  (Greek symbol mu) = dynamic viscosity \(\large{\frac{lbf-sec}{ft^2}}\)   \(\large{Pa-s}\)
\(\large{ \eta_r }\)  (Greek symbol eta) = relative viscosity \(\large{\frac{lbf-sec}{ft^2}}\)   \(\large{Pa-s}\)
