HYDRODYNAMIC STUDIES ON SLURRY TRANSPORT THROUGH SMOOTH PIPELINES

Abstract

Slurry transportation has become a convenient and efficient mode of transportation for wide range of materials, due to its economic viability and relatively lesser pollution potential.The important point in design of a slurry pipeline is the power requirement , which need pressure gradient to be calculated before the pipeline is laid. Various correlations are available for this purpose e.g given by Zandi & Govatos, Turian at al, Durand at al, but these donot consider effect of the particle size distribution of the material to be transported. So in present work the effect of the size distribution is studied with help of coefficient of drag . In addition a mathematical model has 'been proposed to calculate the pressure gradient for re- establishment of the slurry. The slurry consisted of Baryte particles in order to behave as settling slurry with particle size range 40 #Am to 1000 g&m and velocity range of 0.3m/s to 1 . 6m/ s .The pipe used was P. v. c of 46 mm. I.D. Concentrations of the slurry used were 5, 10%, 15%, 20°x, by weight...
