Speed and flow rates of water flow (pulp) in drainage pipelines at various diameters and slopes are analyzed. Speed regime for transporting washed-out sediments, hydraulic slopes of pipelines to form the necessary transporting flow rate, the influence of the flushing hose on the speed and flow rates of the flow of washed-out sediments are defined.
