1D steady, incompressible and inviscid air flows inside a pipe, as shown in Figure 2. The air density is 1.22 kg/m3. The section area at the inlet is 6 m2. The air speed at the inlet is 20 m/s. The temperature at the inlet is 10 °C. The section area at the outlet is 1.5 m2. A; V T 1 1 Ao Figure 2 (a) Determine the air pressure and Mach number at the inlet.
