Curb opening inlet capacity
WebHowever, the capacity of the inlet extension when submerged regresses into only 23% of the expected capacity. Experimental data from this study and data reported in the literature was provided in the Appendix to facilitate future research on curb inlets hydraulics. WebThe capacity of a curb-opening inlet in a sag depends on water depth at the curb, the curb opening length, and the height of the curb opening. Curb inlets operate as weirs to depths equal to the curb opening …

WebThe interception capacity for curb inlets is computed using the following equation. The equation also applies to slotted inlets. Where: LT = curb opening length for 100% capture in ft (m) KT = 0.6 (0.817) Q = gutter flow in cfs (cms) SL = gutter slope, longitudinal in ft/ft (m/m) n = Manning’s n-value Se = equivalent cross slope Where: WebDeck drainage scuppers in bridge barrier railings on grade are designed as curb-opening inlets. To determine the capacity of a scupper, the length of curb-opening inlet required for total interception of the gutter flow is first calculated. Then, the efficiency of the actual scupper opening is calculated to determine its capacity. L T = K Q0.42 ...
