WebDesign of storm water sewer where ks = 0.6mm and minimum velocity = 1.0m/sec. Length of pipe = 1200m. Fall to outlet = 15m => gradient of 1:80. Design Discharge 0.1m³/sec. Determine pipe size when flowing full. Pipe size required is >225mm Ø, next available size is 300mm Ø. Check velocity for 300mm Ø pipe @ gradient of 1:80 = 1.7m/sec. Web2 Mar 2024 · concentrated flow collecting in swales, small rills, and gullies. Shallow concentrated flow is assumed not to have a well-defined channel and has flow depth of 0.1 to 0.5 feet. It is assumed that shallow concentrated flow can be represented by one of seven flow types. These flow types are shown in Figure 2B-3.01 and Table 2B-3.02.
