How can you reduce the drag on something moving through the air?
Answers
Answer:
To reduce the drag on something moving through the air one can:
--Make it more streamlined,
--Reduce its speed (very effective)'
--Reduce it's cross-sectional area,
--Add boundary layer blowing,
--Suck the boundary layer.
--Coat it with a low friction layer (Teflon, wax).
--Go to higher, less dense air,
--Go to hotter air.
Reduce Drag
Explanation:
The friction when something moves through a liquid or gas is called a drag. Shapes that are designed to reduce drag are called streamlined shapes. They resemble a bird in flight or a fish. Cars, airplanes, rockets and speedboats are all shaped in such a way that they are streamlined to reduce maximum drag, so friction is minimum on these objects.
Other ways to reduce drag is to travel at reduced speed with minimum cross-sectional area. The vehicle can also be coated with materials that reduce friction like Teflon or wax. Travelling at less dense air or higher altitudes also helps reduce friction.
