Flow length
WebNote: Each subcatchment can contain multiple flow segments as required to model the entire flow path. The 300 foot limit on sheet flow does not restrict the total flow path or the subcatchment size. Additional segments of other flow types can be used to handle any required length.

WebApr 25, 2024 · Different plastics have different flow length ratio, and the smaller the flow ratio, the worse the fluidity will be. When designing small and medium-sized molds, it is generally not necessary to calculate the flow length ratio, but for large molds, the calculation of the flow length ratio cannot be ignored.
