Lee correlation is the empirical correlation for the gas viscosity published in 1966.
Math & Physics
Why the Lee correlation?
- = gas density, g/cm3
- = gas viscosity, cp
- = gas molecular weight, dimensionless
- = pressure, psia
- = gas specific gravity, dimensionless
- = temperature, °R
- = gas compressibility factor, dimensionless
