In horizontal dense‐phase slurry transport the pressure gradient is the sum of two components. The particle‐contact component, which was evaluated previously, is independent of flow velocity. It is now shown that the second component can be found in terms of a friction factor which depends on a Reynolds number based on flow velocity and particle diameter. The form of the dependence has been evaluated from theoretical considerations, and the results show a gratifying accord with the experimental data. In addition to dense‐phase flow, the findings should be applicable to other cases with a sliding bed of solids.
