what is drag ? how can it be reduced ?
Answers
↪here's your answer....
✴Drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.
_________________________________
To reduce the drag:
1)Make it more streamlined,
2)Reduce its speed (very effective)’
3)Reduce it’s cross-sectional area,
4)Add boundary layer blowing,
5)Suck the boundary layer
6)Coat it with a low friction layer (Teflon, wax).

Answer:
Drag is the result of fluid friction.
Explanation:
The resistance that a body encounters when moving through a fluid, such as air or water, is known as a drag force. In opposition to the direction of the incoming flow velocity, a drag force operates. Skin friction is the primary hypothesis for the origin of drag. All of the solid object's components come into touch with the fluid as it flows through it. There will be a tremendous amount of drag if the surface of the solid is very rough and the fluid is highly viscous. On the other hand, a low drag force is produced when a low-viscosity fluid and a smooth surface come into contact while maintaining the same form.
One can do the following to lessen the drag on an object flying through the air:
- Make it more efficient,
- Reduce its speed (which is particularly effective); decrease the area of its cross-section;
- Blown boundary layer in,
- The border layer is sucky.
- Apply a layer of low friction over it (Teflon, wax).
- a higher, less congested altitude
- Go where it's hotter.
