Figure Legend:
Fluid apparent viscosity (SI units and Oilfield units) versus wall shear rate for base fluid and fluids mixed with material 1. Straight lines (except base fluid) show the estimates obtained from the modified Einstein viscosity model. Shear rate range spans the laminar and turbulent flow.
