L41022 Flow of Natural Gas Through High-Pressure Transmission Lines

Numerous data on gas flow through pipe lines under many conditions of operation were obtained from carefully conducted tests, and these data, together with other available information, were analyzed carefully to obtain practical information for the use of operators in designing pipe lines and determining the effects of different operating conditions on pipeline capacities. In other words, the investigation was primarily an engineering study of representative natural-gas transmission lines operating under numerous conditions of flow.

For the purpose of presentation the discussions in this bulletin have been arranged generally to include, first, a listing of pipeline formulas used by different investigators; second, a discussion of flow tests made by the writers on commercial and experimental pipelines, including methods of testing and of analyzing flow data; and third, a discussion of the application of flow data to commercial pipeline transmission problems. Detailed mathematical development of formulas is included in appendixes with appropriate references in the main text of the bulletin.
