Deformation drag, which is caused by widespread deformation of fluid around the immersed body____________________?
Correct answer: B. Occurs when NRe is very small
- A. Is primarily a friction drag
- B. Occurs when NRe is very small
- C. Is independent of body length
- D. Depends mainly on cross-sectional shape
Explanation
Deformation drag is associated with viscous flow in which the fluid is deformed throughout a broad region around the body, characteristic of very low Reynolds number. Shape-dependent form drag is more prominent at higher Reynolds numbers.
