ABSTRACT
The pipeline transportation of powder in the gaseous state is known as pneumatic transport. The advantage of pneumatic transport is the pipeline transport which allows for a flexible route, saves space, is not affected by surroundings, and does not affect the surroundings. Therefore powder may blow out if there is a leak in the system. Hydrotransport of particulate materials is an acknowledged alternative to conventional forms of transport, such as pneumatic or mechanical conveying. The slurry transportation system for a given conveying capacity is usually designed by determining the pipe diameter and estimating the frictional loss. Slurry flows are categorized into two groups: Homogeneous or non-settling slurries and Non-homogeneous or settling slurries. Non-homogeneous slurries cause the settling of solid particles. Thus, the velocity field and particle concentration distribution are significantly different between horizontal and vertical tube flows. The closed system is used for transporting materials like toxic, explosive, and hygroscopic powders by circulating an inert gas such as N2.
