35 + 9.81 (0.3824 – 7-2) = - 49.54 kPa. i.e.Pg=-49.54 kPa. This shows that the given pressure at A, 35 kPa is gauge pressure and hence there is vacuum at point B. (Ans.) Example 6.5. An open circuit wind tunnel draws in air from the atmosphere through a well contoured nozzle. In the test section, where the flow is straight and nearly uniform, a static pressure tap is drilled into the tunnel wall. A manometer connected to the tap shows that the static pressure within the tunnel is 45 mm of water below atmosphere. Assume that air is incompressible and at 25°C, pressure is 100 kPa (absolute). Calculate the velocity 1,-25°C in the wind tunnel section (Refer to Fig. 6.6). Density of Po-100 kPa water is 999 kg/m and characteristic gas constant for V-0 Test section 207 4e CATE
