Weber number is significant and is concerned with the_________________?
Correct answer: D. Dispersion of liquid in liquid
- A. Solid-liquid mixing
- B. Liquid-liquid mixing
- C. Suspension of solid in liquid
- D. Dispersion of liquid in liquid
Explanation
The Weber number compares inertial forces with surface-tension forces, so it is especially important when droplets are formed or broken during liquid-liquid dispersion. Solid suspension is more commonly assessed using criteria involving the Froude number and settling behaviour.
