Question: 1 2 - 4 9 E Air enters a converging - diverging nozzle of a supersonic wind tunnel at 1 5 0 psia and 1

12-49E Air enters a converging-diverging nozzle of a supersonic wind tunnel at 150 psia and 100F with a low velocity. The flow area of the test section is equal to the exit area of the nozzle, which is 5ft2. Calculate the pressure, temperature, speed, and mass flow rate in the test section for a Mach number Ma=2. Explain why the air must be very dry for this application. Answers: 19.1 psia, 311 R,1729fts,1435lbms
