4.2 Fluid Friction Notes
... The fluid pressure in the wake is less than the fluid pressure in the flow. The lower pressure in the wake causes a force to act on the object (boat or car) in the opposite direction to its velocity. This pressure difference in a wake is called pressure drag. Frictional drag and pressure drag b ...
