This paper demonstrates the usefulness of treating subsonic Fanno flow (adiabatic flow, with friction, of a perfect gas in a constant-area pipe) as a polytropic process. It is shown that the ...

Models in reduced variables are useful tools for the description of the physical world, in that a single formulation relates to a whole set of configurations. For instance, let, , be the density ...
