For the case that and equation (8.36) is reduced into the following approximation
Solving for results in
This relationship shows the maximum limit that Mach number can approach when the heat transfer is extraordinarily fast. In reality, even small results in a Mach number which is larger than 4.5. This velocity requires a large entrance length to achieve good heat transfer. With this conflicting mechanism obviously the flow is closer to the Fanno flow model. Yet this model provides the directions of the heat transfer effects on the flow.
