Chemical Engineering > GATE 2026 > Packed Column Flooding
The flooding velocity curves for two different structured packings are shown in the figure. The ratio of mass velocities of liquid (Gx) to that of the gas (Gy) is 1.27. The density of the liquid (Οx) is 1200 kg mβ3 and that of the gas (Οy) is 1.2 kg mβ3. For both the packings, the allowable superficial vapor velocity is 60% of flooding velocity (u0,F). The ratio of allowable mass velocity of the vapor in packing P to that in packing Q is _____________ (rounded off to one decimal place).
Correct : 1.5
