JoshTheEngineer | Pitot-Static Error: Compressible vs. Incompressible @JoshTheEngineer | Uploaded October 2017 | Updated October 2024, 1 hour ago.
How do calculated velocities change from pitot-static measurements when we assume an incompressible versus a compressible flow? In this video, we will look at the differences between the two equations that can be used to calculate velocity from stagnation pressure, static pressure, and density. Then we will go through both a low speed and a high speed case to show how the calculated velocities differ.

===== NOTES =====
► This video only shows how velocities differ when making the assumption of incompressible versus compressible flow.
► I'm assuming the only thing that changes between the two cases is the measured stagnation pressure (and that the measured static pressure and the density remains the same).
► A full discussion of how pitot-static tubes work is saved for another video.
