The particle relaxation (or response) time, t, is a measure of particle inertia given, in the Stokes regime, by t = Δ ρsd2 /18 μ. WebbHowever, the slurry velocity at the bottom of the pipeline is significantly smaller than that at the top when the sand concentration and diameter reach 30% and 300 m, respectively. It indicates that the sand deposition at the bottom of the pipe declines the slurry velocity and transport capacity. inamos yateley manor
