The part of drag that is due directly to wall shear stress ?w is called the skin friction dragFD, friction since it is caused by frictional effects, and the part that is due directly to pressure P and depends strongly on the shape of the body is called the pressure dragFD, pressure. For slender bodies such as airfoils, the friction drag is usually more significant.
What will be an ideal response?
