This is the answer I was looking for, which I could not find in textbooks. As you say, it is surprisingly straightforward. Thank you very much!

OK, I have read all the Fanno flow equations, I understand mass and enthalpy conservation for adiabatic flows give the result that friction causes Mach number go to 1... But I cannot think of a physical explanation for the counter-intuitive fact that friction both accelerates and cools the...
