Problem 6 Answer the two questions that were asked at the end of the Lab 1 Prep Video: Video 1 - Review of Wind Tunnel and Instrumentation. These are provided below for your convenience. (a) Is the static pressure inside the wind tunnel test section positive gage pressure, zero gage pressure, or negative gage pressure? Provide analysis to justify your answer. (b) It appeared as though the static pressure difference along the contraction was nearly identical in magnitude to the dynamic pressure inside the test section, i.e., PL – PC Žpu? This was no mistake associated with human error (e.g., not correctly setting the pressure selector). Can you explain the similarity in the two pressures? Provide analysis to justify your answer
