Scouring velocity fps
WebNov 14, 2008 · The minimum velocity of 2 fps - 3 fps shall be maintained as a self-cleaning velocity for storm drainage system. In a County, the design criteria for flow velocity is 2 fts and 3 fps for full and half-full flow conditions, respectively. Does this mean that we can assume full pipes with free outfall, e.g., Full Free Flow Velocity? WebFeb 8, 2005 · 2 fps is a commonly specified and recommended minimum scour velocity for raw sewer water. It is specified for force mains in the PA Domestic WW Facilities Manual on page 34. Lindbergs CERM on page 28-5 states that 1.5 fps will keep mixed liquor solids in suspension, and 2 fps will allow resuspension of settled MLSS.
