Any Suggestions on Gas Pipe Sizing and Pressure Loss Analysis

[BravoCompany]

I find that typical sizing tables for gas piping are not thoroughly informative for purpose of sizing pipe design. Does anyone have a suggestion that would allow a section by section calculation to accurately determine pressure drop based on demand and pressure?

To clarify my above statement, the gas tables provide the designer simply with a result based on preestablished values which may not accurately represent a piping network. Basically they speak to given pressure, material type, pipe size and simply answer with a maximum allowable demand within an allowable acceptable pressure drop. These tables are a design aids, but really do not provide a means of calculation.

I welcome any information or related discussion that others may wish to offer.

Thanks
