β¦ Synopsis
The published methods for calculating pressure gradients for the flow of coarse particles in suspension in a horizontal pipeline have been critically examined and have been found to show considerable inconsistencies. Experimental techniques have been developed for the measurement of two in-line parameters, particle concentration and liquid velocity, in order to obtain a better understanding of the transport mechanism.

Hydraulic transport studies with coal and copper ore have been carried out in a 0.0254 m and a 0.01 9 m diameter pipeline to observe the effect of solids concentration, surface characteristics and particle size distribution on pressure drop. The coarse coal showed a lower pressure drop than the fine
