Viscosity of a Slurry

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	\(\large{\frac{lbf-sec}{ft^2}}\)	\(\large{Pa-s}\)
