Pressure drop (Δp) and the superficial gas mass velocity (G) in case of packed absorption tower operating in the preloading range are related as_________________?
Correct answer: C. Δp = G2
- A. Δp = G
- B. Δp = G0.5
- C. Δp = G2
- D. Δp = 1/G0.6
Explanation
In the preloading region, the packed-bed pressure drop is dominated by gas friction and varies approximately with the square of superficial gas mass velocity, Δp ∝ G². This gives the stated relation.
