Industry uses Fanno equations for analysis of behavior of compressible gas in a duct. In the analysis, normally source gas state is given instead of Mach number at inlet cross section of duct, which is to be given in text book analysis of school. Further, the analysis is not be calculated...
However, only three of the above four quantities are independently given, since the steady Fanno flow problem involves three first-order differential equations. Therefore, the problem has three degrees of freedom. The theory in this note shows an algebraic equation that determines the fourth quantity...
From theory, the differential of every flow-related quantity is expressed as a function of Mach number and friction factor. One-dimensional flow numerical models can be derived by discretizing Fanno equations. However , theory does not assess how to evaluate friction, while the model works ...
For example, the pipe block models its internal fluid volume as a single unit and implements the integral form of the conservation equations to determine the aggregate fluid states of that volume. As such, it is less accurate than the analytical Fanno model which incorporates the continuous ...

discusses the Fanno model for quasi-one-dimensional flow of gas in a tube, in situations where the flow is turbulent and the tube is long enough for wall drag to be important. Based on appropriate scalings and with associated boundary conditions they derive equations for similarity solutions ...
