How do you calculate sewer line capacity?
6.2.1.1 Pipe Capacities The Continuity equation and the Manning equation for steady-state flow can be used to calculate flow in a sewer pipe: Continuity Equation: Q = V*A Where: Q = peak flow, cubic feet per second (cfs). V = velocity, feet per second (fps). A = cross-sectional area of pipe, square feet (sf).
