A slurry piping or pipeline system consists of pipelines, valves, and most importantly slurry pumps. A slurry is nonhomogeneous, unlike the liquid or gas phase. Hence, the flow of slurry inside a pipe or pipeline system is very much different and they need special considerations. To flow inside a pipeline, the slurry has to overcome a ...
