In a packed bed absorption column, the channelling will be noted by the ____________________?
Correct answer: B. Sharp drop in pressure drop
- A. Increase in flow rate
- B. Sharp drop in pressure drop
- C. Sharp rise in pressure drop
- D. None of these
Explanation
Channelling causes the fluid to bypass much of the packing, reducing the effective wetted area and flow resistance. The resulting sudden decrease in resistance appears as a sharp drop in pressure drop.
