Orifice discharge coefficient swmm
Witryna8 cze 2024 · In reality, the inlets collect urban runoff and discharge it into the pipe system under drainage conditions 25, and the weir and orifice equations are adopted to compute the exchange discharge. WitrynaThe discharge coefficient - cd - varies considerably with changes in area ratio and the Reynolds number. A discharge coefficient cd = 0.60 may be taken as standard, but the value varies noticeably at low values of the Reynolds number.

WitrynaCoefficient of discharge for various devices are: ⇒ Venturimeter – 0.95 to 0.98 ⇒ Orifice meter – 0.62 to 0.65 ⇒ Nozzle meter – 0.93 to 0.98 ∴ Coefficient of discharge for nozzle meter lies between venturi meter and orifice meter. Witryna7 paź 2010 · The Side Outlet orifice has Weir flow until the Orifice is full but the Bottom Orifice has Weir flow until the Critical Height which is usually shorter than the maximum depth of the orifice. For a circular orifice the Critical Height is: Critical Height = Orifice Discharge Coefficient / 0.414 * Orifice Opening / 4
