Question

Difference between skin friction and form friction

Answer 1

The drag which is created because of the shape of the solid body (or aircraft) and area of cross section, is called form drag.


Every solid body, regardless of how smooth its surface is, it has roughness or imperfections or surface irregularities.
When a fluid flow past the surface of any solid, it experiences resistance against the direction of the flow. This friction is called skin friction drag.
