Question

What are some ways to reduce parasite drag?

1) Using streamlined shapes
2) Reducing surface roughness
3) Minimizing gaps and openings
4) All of the above

Answer 1

Some ways to reduce parasite drag include using streamlined shapes, reducing surface roughness, and minimizing gaps and openings.

Step-by-step explanation:

Some ways to reduce parasite drag include:

1. Using streamlined shapes: By designing objects or vehicles with shapes that minimize resistance to airflow, the amount of drag can be reduced. This can be seen in examples like aerodynamic car designs and streamlined bird and fish shapes.
2. Reducing surface roughness: Smoother surfaces create less turbulence and decrease drag. This can be achieved by employing techniques like polishing surfaces and using specialized coatings.
3. Minimizing gaps and openings: Sealing gaps and openings in objects or vehicles helps prevent air from getting trapped and causing additional drag. This can be done by using materials that create a seamless surface or by adding covers or fairings.

Furthermore, technological advancements in sporting equipment, such as dimpled golf balls and bodysuits for swimmers, demonstrate the pursuit of reduced drag to achieve better performance.
