A theoretical model is derived which permits the analytical calculation of the friction factor-Reynolds number curves for non-Newtonian slurries flowing isothermally in smooth pipes. This model is based upon the Bingham plastic rheological equation of state. A change of mechanism in the transition phenomenon is observed to occur for N/sub He/ = 5 (10/sup 5/), where N/sub He/ is the familiar Hedstrom number. Below this value turbulence is suppressed relative to Newtonian flow, while above this value the transition is delayed but turbulence is enhanced relative to Newtonian flow. A set of theoretical design curves of friction factor versus Reynolds number covering laminar, transitional, and turbulent flows is calculated and presented for a range of N/sub He/ values from 10/sup 3/ to 10/sup 9/.
