Nomenclature | Q=Liquid flowrate at orifice (m3/s) C=Orifice coefficient (-) A_{1}=Orifice area (m2) h=Height of liquid from top of tank to middle of orifice (m) g=gravity acceleration (m.s^{-2}) |
Usual values | g=9.81 m.s^{-2} C=0.6 for non profiled orifice |
Related | Time to empty a tank t_{v}=Time in s to discharge a tank up to the level of the orifice (s) H=Height of liquid at t=0 (m) |
