Abstract
Consistency curves of procaine penicillin G inaqueous suspension were measured with varying concentrations. When measured at a small rate of shear, a non-Newtonian flow was observed but a Newtonian flow was observed at a greater rate of shear. In the region of this Newtonian flow, a relationship represented by the Robinson equation, with relative sedimentation volume measured in centrifugal field as the parameter, was found to exist between relative viscosity, ηr, and volume fraction of dispersed particles, φv
