A discussion is presented regarding the use of real gas property data (i. e., data characterized by temperature and pressure dependence) in the analysis of one-dimensional, compressible, fluid flow problems. In particular, methods are suggested for the mathematical treatment of several commonly encountered processes, including isentropic flow, the generalized flow process (of which the Rayleigh and Fanno lines are special cases), and sub- and super-sonic flow through real nozzles. The philosophy of calculation is graphically demonstrated by means of simple logic flow diagrams. Special emphasis is placed upon the use and interpretation of tabular gas property data such as that presented in National Bureau of Standards Circular 564. A unique interpolation scheme is presented which preserves the continuity of both data and first derivatives. Applications of the described procedures are presented in the Appendix in the form of appropriate FORTRAN II digital computer code listings.
