From what I understand, static pressure is just the pressure of still air and acts perpendicular to the airflow and surface. An airplane will feel static pressure regardless of whether it is moving or not. If there was airflow moving through a pipe, then static pressure is the pressure exerted on the walls of the pipe.
On the other hand, dynamic pressure is the pressure that results from the motion of air, or its kinetic energy. It acts parallel to the flow of air. Would it be appropriate to say that dynamic pressure is the pressure exerted on the windward side of a flat plate in the pipe like this:
If this illustration is correct, then does that mean maximum dynamic pressure is felt by a surface when it is perpendicular to the flow?
