Q:
Does the smoothness of a surface affect the pressure drag?
A:
The smoothness of a surface affects friction drag. Pressure drag is generated when air flowing past an object pushes harder against the front than the back, resulting in a backward force. Friction drag occurs when two things rub together, so the smoothness of the surface would make a difference.
