Webpressure gradient, capsule velocity, capsule drag and lift. The new theory can predict the capsule flow behavior under a wide range of conditions not possible with previous theories. The Center also developed a means for predicting the unsteady flow and pressure surges (water hammer) in hydraulic capsule pipelines (HCP) generated by rapid valve Webpipelines, carrying a train of capsules. Tomita et al [6-7] conducted a series of analytical studies on the flow of cylindrical capsules, focusing only on the velocity and the trajectory of the capsules, in a hydraulic pipeline. However, the …
WebPipeline design includes a selection of the route traversed by the pipe, determination of the throughput ( i.e., the amount of fluid or solids transported) and the operational velocity, calculation of pressure gradient, selection of pumps and other equipment, determination of pipe thickness and material ( e.g., whether to use steel, concrete, …
WebJan 1, 2013 · Measurements were conducted on capsule concentrations of 5%–20% at bulk velocities ranging from 0.2 to 1.0 m/s. The effect of the bulk velocity and diameter ratio on the velocity ratio was demonstrated.
