Weber number is the ratio of inertial force to _____________ force?
Correct answer: A. Surface tension
- A. Surface tension
- B. Gravity
- C. Viscous
- D. Elastic
Explanation
The Weber number compares inertial forces with surface-tension forces, typically written as We = rho V2 L/sigma. Gravity corresponds to the Froude number, while viscosity corresponds to the Reynolds number.
