← ScienceWhich outcome results when pitot tube placement is misaligned at high angles within a compressible airflow?
A)Spurious readings misreport dynamic pressure✓
B)Turbulence reduces velocity profile variance
C)Bernoulli's equation becomes locally invalid
D)Viscosity effects dominate pressure measurement
💡 Explanation
Spurious readings arise because flow separation causes incorrect static and dynamic pressure measurements; **flow separation** disrupts streamline assumptions inherent for computations utilizing these pressure values. Therefore, dynamic pressure deviates, rather than velocity profile improvements, occur, because viscosity or Bernoulli equation failures at small flow separations are less significant.
