Design of gas networks problem from practice | Prilog projektovanja gasnih distribucionih mreža

Accent is on determinination of appropriate friction factor and on selection of a representative equation for natural gas flow under presented conditions in the network. In this paper is shown method for the hydraulic solution of a loopes gas pipeline-network for valuable condition in the network. Innapropriate usage of friction factor, aequally as innapropriate usage of gas flow equation can lead to incaccurate final results. Causes for these deviations are investigated in one real case, and improved and more accurate procedure is shown.
