Studying the Pipeline Transport of Sapropel During Operation of Dredgers with Screw Pumps

Abstract

A method for calculating the pressure gradient during transportation of sapropel of natural viscosity through a pipeline of circular cross-section is described. The rheological properties of sapropel allow considering it a viscoplastic fluid. The effect of the ultimate shear stress, plastic viscosity of sapropel, and the inner diameter of the pipeline on the pressure gradient is studied.
