- Expert Q&A Done Equipment: STATIC VELOCITY TOTAL Pat Image 1. The tabletop air nozzle was used to measure the flow of air via the Pitot-tube positioned in the middle of the nozzle The pitot-static-tube is connected to all three manometers by a plastic tube. The first manometer calculates the static pressure through the difference in the atmospheric and static pressure readings. The second manometer calculates velocity pressure through the difference in static pressure and total pressure readings. Lastly, the third manometer calculates total pressure through the total and atmospheric pressure readings.

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 pressure is 100 kPa (absolute). Calculate the velocity in the wind tunnel section (Refer to Fig. 6.6).
