Abstract
A method for maintaining suitable velocity or velocity range in a slurry pipeline system of the type with a water pipeline return and slurried material pipeline output with more than one slurry injection point. A single set of primary pipelines, one water and one slurry, is able to serve multiple points of hydraulic injection by means of slurry pipeline flowmeters downstream from each slurry injection water bypass junction, with each flowmeter actuating water control valves to bypass water to the slurry pipeline at the respective junction so as to maintain slurry pipeline velocity within prescribed limits.
