Negligible ρ_g = MW P/ZRT ρ_g = MW P/ZRT Viscosity μ₁ = Ae^B/T Negligible Significant only for >10 bar Vapor pressure P* = ae^b/(T+c) – – –

      Note: T is temperature (K), T_c is the critical Temperature (K), T_b is the normal boiling point (K), MV is molecular weight, P is pressure, Z is compressibility, R is the gas constant, and P* is the vapor pressure.
