A converging nozzle feeds an insulated square duct (L = 224 ft, W = H = 8.0 in, f = 0.02) with air flowing steadily at 7200 lbm/min. The inlet stagnation temperature and stagnation pressure are respectively equal to 116 deg F and 190 psia. Calculate the exit Mach number, exit pressure, exit stagnation pressure and exit stagnation temperature. Ans. 0.67, 70.2 psia, 94.9 psia, 116 deg F.
