The length of straight rectangular weir used on cross-flow trays is generally ________________ the column diameter ?
Correct answer: A. 0.6-0.8 times
- A. 0.6-0.8 times
- B. Equal to
- C. Twice
- D. 2 ft irrespective of (for column > 3 ft diameter)
Explanation
The straight weir on a cross-flow tray is usually shorter than the column diameter, with a length of approximately 0.6 to 0.8 times the diameter. This leaves room for liquid flow patterns and tray construction requirements.
