Pumping a simulated sediment slurry at a low water content has been investigated at the GIW Hydraulic Testing Laboratory in a 3 inch (0.075 m) diameter loop with a centrifugal pump with an auger-like inducer. The results and earlier reported data from the Laboratory indicate that viscous sediments characterized by yield stresses in the range of about 2 to 4 psf (100 to 200 Pa) can be pumped effectively with centrifugal pumps. With yield stresses of up to 4 psf (200 Pa), the pressure requirement to overcome pipe friction for pipeline diameters of 4 and 16 inch (0.1 and 0.4 m), may be 0.35 and 0.09 psi per ft ( 8 and 2 kPa per m) of pipeline, respectively. Several pumps in series are therefore required also for moderate transportation distances. The results indicate that centrifugal pumps can be a cost-effective alternative for handling and transportation of sediments at a low water content.
