where:
Wm = Mass flow rate of liquid phase, lb/hr-ft2 of total pipe cross-section area
G = Mass flow rate of gas phase, lb/hr-ft2 of total pipe cross-section area
ρL = Density of liquid phase, lb/ft3
ρg = Density of gas phase, lb/ft3
μL = Viscosity of liquid phase , cp
μg = Viscosity of gas phase , cp
γ = Surfance tension of liquid , dynes/cm
