Analytic equations for the flow of compressible fluids in conduits with friction are awkward to solve, since the variables involved usually necessitate trial and error solution. A study of the situation indicated that a series of graphs for different values of the specific heat ratio would eliminate the trial and error solution.
The purpose of this paper is to present in graphical form a solution of the equations relating the ratios of the pressure and temperatures in adiabatic flow of compressible fluids to the friction and velocity.
The equations for adiabatic flow of compressible fluids in horizontal ducts of constant cross section have been employed to calculate a series of values of the pressure ratio and the friction at each of several Mach numbers for each of three specific heat ratios. The temperature ratio has also been calculated for each of several mach numbers for each of the three specific heat ratios.
The graphs make it possible to calculate the pressure drop and temperature drop of compressible fluids, in adiabatic flow in horizontal ducts of constant cross section with friction, without resorting to trial and error solution.
The results are presented graphically on pages 9 to 11.
