= 7. An open circuit wind tunnel used for testing airplane models pulls in air at P = 95 kPa and Too 17 °C from the atmosphere through a well-contoured nozzle as shown in the figure below. In the test section, where the flow is straight and nearly uniform, a static pressure tap is drilled into the tunnel wall and a manometer is connected to the tap. a) Determine the manometer reading h when the velocity in the test section is 100 km/h. Note that there is a 3-cm column of oil (SG = 0.9) on the water (Pw = 1000 kg/m³) in the manometer. b) Determine the difference between the pressure at the nose of the model (stagnation pressure) and the pressure in the test section. wind tunnel wall AIR FAN 100 km/h P=95 kPa T-17 °C water 1 oil open to the atmosphere 3 cm
