The solid concentration was measured to determine particle velocity. The total solid concentration ranged from 5% to 45% by volume. A correction factor of (voidage) °z applied to the model of Garside and A1-Dibouni (1977), gives satisfactory results for reduced velocity at intermediate particle Reynolds number. The data obtained for monodisperse suspensions were tested against the published models. The modified model gives a mean sum of squares of residuals 0.0004 as well as better results than the other models in the flow range 150 < Re < 2200.

The model obtained was tested against the experimental data obtained from a countercurrent flow system and was found to give an excellent fit. The Reynolds number ranges between 4 and 1300. The model predictions were compared with those of other published models. The model predictions have shown an improvement and do not have the limitations present in the other models.
