Air flows steadily between two cross sections in a long, straight section of \(0.1-\mathrm{m}\)-inside-diameter pipe. The static temperature and pressure at each section are indicated in Fig. P5.9. If the average air velocity at section (1) is \(205 \mathrm{~m} / \mathrm{s}\), determine the average air velocity at section (2).
