A pipeline slurry friction loss model consisting of three regimes was initially proposed by Wilson then extended to four components consisting of fluid, pseudo‐homogeneous, heterogeneous, and fully stratified regimes. The weighting technique using up to four regime‐related components often works well for friction loss estimations based on simple input data and model parameters. This also holds for the Hydraulic Institute's pump performance derating procedure for settling slurries. The comparisons and discussion focus on coarse particle slurries and some cases where the modelling estimations for pipeline and pump performance were not particularly accurate.
