Problems involving adiabatic flow of compressible fluids in horizontal conduits of constant cross-section usually require tedious trial and error solutions. Although several somewhat simplified methods have been developed, most of these methods are not ideally suited for problems involving flow between two sections of a conduit.

The graphical solutions presented in this paper, relating pressure and temperature ratios to friction and initial Mach numbers, have been developed specifically for flow between sections of a conduit. Use of the graphs requires only the knowledge of initial conditions and determination of the friction factor.

Initial velocities from 30% to 70% of the initial acoustic velocity have been presented in this paper. Graphs for initial velocities of 5% to 30% of the initial acoustic velocity have previously been presented by Straub.(7) Combination of both papers provides a continous range of initial velocities from 5% to 70% of the initial acoustic velocity.
