Ratio of inertial forces to surface tension forces is called the _____________ number?
Correct answer: D. Weber
- A. Euler
- B. Froude
- C. Mach
- D. Weber
Explanation
The Weber number compares inertial forces with surface-tension forces, typically written as We = ρv²L/σ. Euler compares pressure and inertial forces, whereas Froude compares inertial and gravitational forces.
