WebSimply calculate the flow ratio for each lane by dividing the design flow rate by the saturation flow rate. Then find the lane with the largest flow ratio. It looks like the north-bound left-turn and straight-through lane is the critical lane for this phase. The critical flow ratio is just the flow ratio for the critical lane (0.5). WebAug 30, 2024 · Estimation of Flow Rates: Design of sewers means to find the diameter (size) and the slope (gradient) of sewers to carry the given amount of discharge providing self cleaning velocity. The velocity in the sewers should be such that there is no silting of solids in the sewers.
