3. Pitot-Static Tube a. A pitot-static tube is placed in a subsonic airflow. The static pressure and temperature in the flow are 96 kPa and 27C respectively. The difference between the pitot and static pressures is measured using a liquid-in-glass manometer and found to be 241 mm Hg (mm of mercury). The measurement is performed at Chulalongkorn University. Find the air velocity: a. Assuming incompressible flow and b. Assuming compressible flow.
