Viscosity (Gas at low pressures; p < 6 bar)

• DEFAULT: TransportPolynomial: (Output details)

  h = å a_i × T ⁱ, where the summation is from i = 0 to nTerms - 1

• Alternative 1: Yaws.PolynomialExpansion (Output details)

  h = å a_i × T ⁱ, where the summation is from i = 0 to nTerms - 1

• Alternative 2: DIPPR 102 (Output details)

  h = A×T ^B / (1+ C/T + D/T ²)

• Alternative 3: PPDS 5 (Output details)

  h = a₀ ×T_r / {1 + a₁ ×(T_r - 1)× T_r^a₂}^1/6; where T_r = T/T_c and T_c is the critical temperature.
