1.2 to 3.8 cms is the value of the ______________________?
Correct answer: D. All A., B. and C.
- A. Downcomer liquid seal in case of a balanced tray design
- B. Static submergence in case of a bubble cap tray for column operating under pressure (≥ 1 atm)
- C. Skirt clearance for bubble caps
- D. All A., B. and C.
Explanation
The range of about 1.2 to 3.8 cm is used as a typical design range for the downcomer seal, bubble-cap static submergence, and cap skirt clearance. Hence all three listed applications are included.
