The long, low tail, for example, is very specific. brushes digital paintingIn fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particula… Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the direction of movement of a solid object such as cars (automobile drag coefficient), aircraft and boat hulls; or acting in the same geographical direction of motion as the solid, as for sails attached to a down wind sail boat, or in intermediate directions on a sail depending on points of sail.

"WebA turbulent slipstream has a lower pressure than the fluid (air or water, pick your poison) around the object, thus decreasing the efficiency at which the object travels through the material. A Laminar slipstream (the kind you want) has a higher pressure than the fluid around the object, thus allowing the object to travel more efficiently through fluid. " - Lowest air drag material
