A
Drag.
5
Q
What is the average thickness of the air pressure area?
A
Between 2mm and 2 cm.
6
Q
What is the stagnation point and where about is it located?
A
The stagnation point is a point in a flow field where the local velocity of the fluid is zero.
It is normally located over the front of the wing but it depends on the angle of attack.
