Did you know?
In fluid dynamics, drag (sometimes called fluid resistance) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between an fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and … WebThe drag coefficient is generally given by the formula CD= 2F D / ρv 2A Where; ρ is the density of the cylinder, FD is the drag force, v is the velocity of the cylinder moving in the fluid, and A is the area of the cylinder. The area of …
WebParasite drag increases with airspeed. Curve "A" shows that parasite drag is very low at slow airspeeds and increases with higher airspeeds. Parasite drag goes up at an increasing rate at airspeeds above the midrange. Curve "B" shows how induced drag decreases as aircraft airspeed increases.
