I have been looking all over the net for answers for the unintuitive relationship between pressure and velocity in Bernoulli's equation and this thread (https://www.physicsforums.com/threads/the-concept-of-pressure-in-bernoullis-principle.585231/) answered most of my questions.
I have one last question lingering in my mind though. What exactly is the difference between static and dynamic pressure?
The examples here: http://www.engineeringtoolbox.com/dynamic-pressure-d_1037.html
Hint that there is nothing magical about dynamic pressure. Same units, same effect.
Except that (from what I think) in contrast to static pressure that pushes in all directions, dynamic pressure only pushes in the direction of its velocity.
It's as if the pressure that was supposed to be pushing in all directions, some of that pressure is being converted into pressure that acts in only one direction by virtue of the shape of the tube?
Is this correct? Or am I wrong?
Thanks
