The thickness of segmental baffles (25 -35% cut truncated plates usually) is generally _____________ the tube wall thickness?
Correct answer: B. Twice
- A. Equal to
- B. Twice
- C. Four times
- D. Half
Explanation
Segmental baffles must be stiff enough to support the tube bundle and resist vibration, so their thickness is commonly about twice the tube-wall thickness. Making them equal to or half the tube-wall thickness would generally be too weak.
