At the same gas flow rate, the pressure drop in a packed tower being irrigated with liquid _______________ that in dry packed tower ?
Correct answer: A. Is greater than
- A. Is greater than
- B. Is lower than
- C. Is same as
- D. Cannot be predicted as data are insufficient
Explanation
An irrigated packed bed has liquid holdup and additional interaction between the gas and liquid phases, increasing resistance to gas flow. Therefore, its pressure drop is greater than that of the same packing when dry.
