SUMMARY
In Fanno flow, the Mach number cannot increase from 1.8 to 1.22 in a constant area duct with friction. The Fanno line indicates that in the supersonic region, the Mach number consistently decreases along the flow path. The initial confusion stemmed from a misinterpretation of the problem statement, but it is confirmed that the Mach number indeed decreases from 1.8 to 1.22 in this scenario.
