Froude number is the ratio of__________________?
Correct answer: D. Inertial stress to gravitational stress
- A. Shear stress to gravitational stress
- B. Drag stress to shear stress
- C. Inertial stress to shear stress
- D. Inertial stress to gravitational stress
Explanation
The Froude number compares inertial effects with gravitational effects, commonly written as Fr = V/√(gL). It is important where free-surface or gravity-driven motion is involved.
