The project shall only use uniform gutter sections as opposed to depressed gutter sections per HEC … WebThe efficiency of a grate is dependent on the same factors and total flow in the gutter. The interception capacity of grate inlets on grade is computed using the following equations: Where: E = efficiency of the grate. Rf = …
WebThe interception capacity of an open-throat curb intake is equal to the efficiency of the intake multiplied by the total gutter flow. The general equation relating efficiency to intercepted flow is: Q i = EQ (Equation 4A-7_1) where: Q i = Intercepted flow, ft 3/s (m /s). E = Intake efficiency. Q = Design gutter flow, ft3/s (m3/s).
