Air at 50 kPa pressure and 400 K temperature flows in a duct at Mach 3.0. A part of the flow leaks through an opening on the duct wall into the ambient, where the pressure is 30 kPa. The maximum Mach number achieved in the discharge is ________ (accurate to two decimal places). (Ratio of specific heats of air is γ=1.4).
Correct : 3.30 to 3.40
