Hydraulic Capacity of Precast Concrete Boxes

stant for the full flow condition. Based on Manning’s Formula, these tabular values are equal to Q/S1/2 for full flow. For any Q/S1/2 value, the size of box required can be read directly. It is important to note that in sewer design, a hydraulic comparison between various shapes cannot be made solely on the basis of cross-sectional areas ................
