sedimentation velocity in pipes and ducts

 The sedimentation rate is the minimum speed that a flow must be to carry, rather than deposit, sediment. The sedimentation velocityis given by Stokes' law $sedimentation velocity pipes ducts$ where w is the speed of sédimentation, ρ is the density (the indices p and f indicate particle and fluid respectively ), g is the acceleration due to gravity, r is the radius of the particle and μ is the dynamic viscosity of the fluid. If the velocity of flow is greater than the deposit velocity ( sedimentation velocity) the aggregate continues downstream The interface for calculating sedimentation rate in the Tools MECAFLUX A minimum speed alert sedimentation can thus be resolved in the interface sizing ducts to detect the maximum diameter does not exceed a project network of fluid loaded. The transport of particles as the aspiration of copal or stormwater must be sized according to the sedimentation rate to prevent particle deposition
