The important dimensional group involved in the power requirement calculation in mixing operation is the _____________ number?
Correct answer: C. Both A. & B.
- A. Reynold's
- B. Froude
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
Mixing power depends on both the Reynolds number, which indicates viscous or turbulent flow, and the Froude number, which represents the effect of gravity and free-surface movement. Hence both dimensionless groups are important.
