With increase in the liquid flow rate at a fixed gas velocity in a randomly packed counter current gas-liquid absorption column, the gas pressure drop___________________?
Correct answer: C. Increases
- A. Decreases
- B. Remains unchanged
- C. Increases
- D. Decreases exponentially
Explanation
A higher liquid rate increases liquid holdup and wetted packing surface, adding resistance to gas flow through the bed. Consequently, the gas pressure drop increases at fixed gas velocity.
