    The viscosity measurement has been made for suspensions consisting of polyethylene beads and silicone oil matrix as a function of mean diameter of beads and shear rate. The relative viscosity is found to increase with increasing the volume fraction of beads and decrease with the mean diameter of beads and shear rate. We also tested several viscosity equations to reproduce the viscosity values of spherical particle dispersed suspension. However, any equation could not reproduce well the experimental viscosity values of suspension measured under various conditions. Some modification is needed by considering some experimental conditions (volume fraction, mean diameter of beads and shear rate). Then, the modified Einstein-Roscoe equation is recommended for reproducing the viscosity values of suspension under various conditions.
