Take density of water = 1,000 kg/m', density of air = 1.23 kg/m', acceleration due to gravity = 9.81 m/s. C2. Air is drawn into a wind tunnel used for testing automobiles as shown in Figure C2. (a) Determine the manometer reading, h, when the velocity in the test section is 100 km/h. Note that there is a 25-mm column of oil of relative density 0.9 on the water in the manometer. (b) Determine the difference between the stagnation pressure on the front of the car and the pressure in the test section.
