How to read this view
What changes when speed doubles?
Transit time over the same distance halves. Dynamic pressure q = ρv² / 2 quadruples at fixed density. Markers move in real time or at the selected slow rate.
Is dynamic pressure the force on an object?
Dynamic pressure is measured in Pa. Force also depends on area, shape and drag coefficient. This page does not convert it to force or assess wind resistance.
Is the illustrated instrument a live measurement?
It displays values derived from your inputs. No physical sensor is connected. The tunnel is illustrative; fan rpm is not mapped to airspeed.
