KW 3 1 - DT 3 1 - 0.930 4.2 Therefore, KW = 1/1.010 = 0.990 Superficial gas velocity at 70% of flooding from above = 20 ft/s for NOR PAC. Superficial gas velocity at 70% of flooding from above = 13 ft/s for Montz Gas viscosity = 0.012 cP and gas density = 0.0370 lb/ft3. From Eq. (6-114), for NOR PAC, N ReV = uV DP V (20)(0.012)(0.03...
