Work on the evaluation of the head loss of slurries flowing in horizontal and vertical tubes is summarized. The slurries used in the investigation were spherical glass beads and lon-exchange resin particles suspended in water. The tube size used was approximately 0.3-in. in inside diameter. Concentrations from zero to approximately 50 wt.% were used. The results are presented in graphical form as head loss in feet of mixture vs. Froude number and a "Z-factor" vs. Froude number. The Z-factor is evaluated as the ratio of the pressure drop of the pure fluid to the pressure drop of the mixture flowing at the same mean velocity. The relation between the Z-factor for turbulent flow and concentration is presented in graphical form for the three directions of flow. (auth
