Reynolds number is the ratio of____________________?
Correct answer: B. Inertial forces to viscous forces
- A. Viscous forces to gravity forces
- B. Inertial forces to viscous forces
- C. Viscous forces to inertial forces
- D. Inertial forces to gravity forces
Explanation
Reynolds number compares inertial forces with viscous forces, commonly written as Re = ρvD/μ. A high value indicates that inertia dominates, while a low value indicates stronger viscous influence.
