Hydraulic Capacity of Precast Concrete Boxes

hydraulic comparison between various shapes cannot be made solely on the basis of cross-sectional areas or peripheries. For two conduits of similar materials and different shapes to be hydraulically equivalent, it is necessary for the factor A x R2/3 to be the same for both. Multiplying this factor by 1.486/n accounts
