A converging–diverging nozzle operates at steady state. Air as an ideal gas with k=1.4enters the nozzle at 500 K, 6 bar, and a Mach number of 0.3. The air flows isentropicallyto the exit plane, where a normal shock stands. The temperature just upstream of the shock is 380.416 K. Determine the back pressure, in bar.

Consider airflow over a flat plate of length l = 1.5 m under conditions for which transition occurs at le = 0.9 m based on the critical reynolds number, re,e = 5 x 10. evaluating the thermophysical properties of air at 400 k, determine the air velocity. (hint: use the tables to find the properties of air)
