> Natural Gas Flow
>
> Recently, LMNO Engineering has been consulting for the natural gas
industry. The LMNO Engineering website currently doesn't have any
calculations specifically for natural gas. We have calculations using the
Darcy-Weisbach method which can analyze gases so long as gas compressibility
is minimal for the pipe run.
>
> Crane TP-410 provides several equations specifically developed for natural
gas flow. They are the Spitzglass, Weymouth, and Panhandle formulas. All
three formulas are empirical. The Spitzglass formula is valid for low
pressure gas having less than 1 psig pressure (69 mbar gage). Weymouth is
valid for high pressure gas, and the Panhandle is valid for 6 to 24 inch (15
to 60 cm) gas lines with Reynolds numbers between 5 million and 14 million.
>
> We receive quite a few e-mail questions about natural gas and are
considering developing calculations using the Spitzglass, Weymouth, and
Panhandle equations. I am interested in any feedback you might have about
whether these calculations would be helpful to you.
