High-Pressure Pipe-Line Research

In estimating gas-pipe-line costs prior to undertaking the detailed design, it has been the practice generally to utilize graphical determinations of such variables as pipe-line diameter, compressor-station spacing, operating pressures, and the like. The graphical method is a time-consuming process, however, entailing the preparation and consideration of a large number of curves. The purpose of this paper is to show the derivation of an empirical equation containing all of the design variables, to which the methods of the differential calculus may be applied to yield a general series of expressions for the most economical design of any pipe line.
