In the case of compressible viscose fluid flow in a duct, the velocity, density and other physical parameters on each cross section are never uniform. Upon analyzing such non uniform flow, however, it is very convenient in practical use if it can be treated as an one-dimensional flow without decreasing the accuracy of the analysis. For this reason, the optimum mean value in a compressible real fluid flow in a duct, is discussed in this paper. By using the arailable present mean values which are based on mass flux, the well-known one-dimensional basic relations of gas dynamics are consistently generalized into the actual flows by simpler relations. The characteristics of the correction factors, which arise in the present treatment, are clarified for Reynolds number and Mach number. The apparent error occuring in the uniform flow analysis can be successfully estimated by the present method.
