What is the typical flow rate for designed gutters?

Reply #22009-08-05

The minimum design flow rate is the flow rate that ensures no sedimentation occurs within the pipeline. The minimum design flow velocity for the sewage pipeline at full capacity is 0.6 m/s. For production wastewater pipelines containing metal, mineral solids, or heavy oil contaminants, the minimum design flow velocity should be increased appropriately; the minimum design flow velocity for open channels is 0.4 m/s. The maximum design flow rate is the flow rate that ensures the pipeline is not damaged by erosion. This value is related to the pipe material; generally, the maximum design flow velocity for metal pipes is 10 m/s, while it is 5 m/s for non-metallic pipes.
