    For a Dp=0.762 m (30 inch) pipe, a particle diameter of d=0.5 mm, a pipe length of 4000 m, a water depth of 20 m and an elevation of 10 m, the relative excess hydraulic gradient curves are given in Figure 10.4-1. The graph shows the homogeneous curve (light brown), the DHLLDV Framework curve for constant spatial volumetric concentration (red), the DHLLDV Framework curve for constant delivered volumetric concentration (dashed green) and the resulting pump curve for the mixture (dark brown). The graph also shows the LDV.
