Air Flows Isentropically From Atmosphere At 101 5kpa And 15 C To A 600mm Square Duct 3279209

air flowsisentropically from atmosphere at 101.5kpa and 15°c to a 600mm square duct where the mach number is 1.6. calculate the static pressure, the velocity, the mass flow rate in the duct and also determine the pressure, velocity at the point with minimum cross section area upstream of this suction. evaluate the minimum cross sectional area
