10. FLOODING POINT GAS FLOW FORCED THROUGH LIQUID CORRELATION WITH P
PACKING FACTORS
Pflood = .115Fp.7
PACKING FACTOR > 60
ASSUMED = Pflood = 2 IN. H20/FT.

11. GAS COLUMN DATA

12. CONCLUSIONS Pflood = 2 in. H20/ft. of packing P(geyser) = 26 in. H20
ENGR.435 COLUMN = 10 in. H20
P(geyser) = 26 in. H20
COLUMN BECOMES INOPERABLE
OPTIMUM OPERATING POINT
1/2 GAS FLOW RATE OF FLOODING
1.5 LBS./MIN
