Frictional drag comes from friction between the fluid and the surfaces over which it is flowing. This friction is associated with the development of boundary layers, and it scales with Reynolds number ...

So the bulk velocity of the fluid must change from whatever its value is far away from the wall to a value of zero at the wall (figure 7). This is called the no-slip condition. Figure 7. Velocity ...

In the process, we learn about a variety of fluid phenomena and its applications such as: supersonic flow and the principles of design of jet engines, viscous boundary layers and the consequent drag ...
