WebThe area of flow section of a sewer required to carry a given discharge can be determined by the following general formula based on the principle of continuity: Q = A x V. Where. Q is discharge in m 3 /s; A is area of flow section in m 2; and. V is velocity of flow in m/s, which may be determined by the various formulae indicated earlier. Web02. nov 2024. · Therefore: V avg = (108.1011g/α) 1/2 x S 1/2 x R 0.3749. Resulting in the following equation, which we’ll call Equation 2 for future reference: V avg = 10.3972 (gS/α) 1/2 x R 3/8.
