> New Calculation - Small Bore Orifice for Gas Flow
> http://www.LMNOeng.com/Flow/SmallOrificeGas.htm
>
> You asked for it! We wrote it! A calculation for gas flow through a
small bore orifice. The calculation will compute flowrate, differential pressure, or bore diameter for gas flow through an orifice installed in a pipe having a diameter between 0.64 cm and 5 cm.
>
> Our calculation is based on the equations and methodology described in
ASME MFC-14M-2001. You may select flange taps or corner taps. The method is valid for pipe Reynolds numbers greater than 1000 and diameter ratios between 0.1 and 0.8 for corner taps (0.15 and 0.7 for flange taps).
>
> As with all of our calculations, a variety of units are selectable from
drop-down menus. Fluid properties are built-in for air, methane, nitrogen, oxygen, carbon dioxide, and other gases. Alternatively, you may enter properties for gases not listed.
