    The paper presents the results of an experimental investigation of capsules conveyed by water in horizontal bend and straight inclined pipes. The effect of pipe curvature and inclination and geometrical and physical parameters of capsules on capsule threshold velocity, capsule/liquid velocity ratio and hydraulic gradient of the system was evaluated. It was found that the capsule/liquid velocity ratio is not significantly influenced by pipe curvature. In an ascending pipe a decrease of the velocity ratio depends on length, angle of inclination and capsule/liquid density ratio; in a descending section of pipe the opposite is valid. The pressure gradient in the bends is substantially higher in comparison to the straight pipe sections. For inclined pipe the pressure gradient increment/decrement depends on the angle of inclination, density ratio, and capsule concentration.
