Data are presented on the flow phenomena associated with the hydraulic transport of right cylindrical capsules, having d/D and L/d ratios, and relative density in the range of 0.49 to 0.82, 4 to 14, and 1.15 to 2.7 respectively, in a 7.6 cm 1.D. vertical pipeline with flow Reynolds numbers up to 3.6 × 10 5 . On the basis of the experimental results the effect of the individual pertinent variables which affect the velocity ratio Rv , pressure gradient ratio Rp and the unit energy requirement E for the capsule are discussed. Semi‐empirical correlations between the capsule velocity and the capsule gradient and the pertinent variables of the system are also presented.
