The Pitot-static tube illustrated in Figure 1 is used to measure the flow speed in a teaching wind tunnel. The manometer fluid is water and the density of the air is 1.225 kg/m³. The manometer tubing and the reservoir are both cylindrical. If L=278 mm, 0 = 20°. dg = 60 mm and dr = 8 mm, determine: (a) the dynamic pressure of the air, and (b) the velocity of the air.
