Air at a temperature of 100°C is under pressure in the large tank shown in Fig. 13–9. If the nozzle is open, the air flows out at M = 0.6. Determine the temperature of the air at the exit.

Nitrogen flows isentropically through the pipe in Fig. 13–10 such that its gage pressure is p = 200 kPa, the temperature is 80°C, and the velocity is 150 m/s. Determine the stagnation temperature and stagnation pressure for this gas. The atmospheric pressure is 101.3 kPa.
