Orifice mass flow rate equation
WitrynaTHE USE OF SUBSONIC ORIFICES FOR MEASUREMENT OF GAS FLOW Thomas A. Cygnarowicz a~d Ronald Corazzi Sept., 1969 An approximate equation is derived for calculation of gas weight flow rate through subsonic orifices for small differential pressures. Comparison to the exact equation shows good correlation even at con- Witrynagiven by Darcy formula: In an orifice, the flow is through a smaller bore dia of the orifice and expanding to a higher dia, on the . downstream Such a stream of gas flow is considered to be an adiabatic expansion. Under such conditions, the mass flow rate is given by Darcy formula : −6 Yd2 ∆p ρ K. Where: 𝒲−mass flow rate,Y−Gas ...
