The minimum baffle height should be ______________?
Correct answer: C. Twice the impeller diameter
- A. Equal to the impeller diameter
- B. Twice the tank diameter
- C. Twice the impeller diameter
- D. 3/4 of the tank height
Explanation
A baffle must extend sufficiently through the mixing zone to suppress swirling and promote radial mixing; a commonly used minimum is about twice the impeller diameter. Smaller heights allow excessive vortex formation and poor blending.
