Liquid gradient over the tray results due to the___________________?
Correct answer: A. Resistance offered to flow of liquids by caps & risers and the flow of gas
- A. Resistance offered to flow of liquids by caps & risers and the flow of gas
- B. Low gas velocity
- C. Large plate spacing
- D. Large reflux ratio
Explanation
Liquid gradient develops as liquid flows across the tray and loses head because of resistance from caps, risers, and the opposing gas flow. Low gas velocity or large tray spacing does not directly produce this gradient.
