Problem 3. The inlet contraction and test section of a laboratory wind tunnel are shown. The air speed in the testsection is U = 50 m/s. A total-head (or Pitot) tube pointed upstream indicates that the stagnation pressure onthe test section centerline is 10 mm of water below atmospheric. The laboratory is maintained at atmosphericpressure and a temperature of -5 °C. (a) Evaluate the dynamic pressure at the centerline of the wind tunnel testsection. (b) Compute the static gage pressure at the same point. (c) Discuss qualitatively how the static gagepressure at the tunnel wall may be different from that at the centerline both in the test section and in thecontraction.flowPitot tubeUtest sectioncontraction

The dynamic pressure can be calculated using the formula:ρU22where ρ is the air density and U is the…
