Surface Tension s (Liquid/Gas)

• DEFAULT: PPDS 14: (Output details)

  s = a₀× t^a₁×(1 + a₂ ×t) , where t = 1 - T/T_c and T_c is the critical temperature.

• Alternative 1: Yaws.SurfaceTension (Output details)

  s = exp(A)×{1 - ( T / T_c )}ⁿ

• Alternative 2: Watson (Output details)

  ln(s/s^o) = a₁ + åa_i ×T_r^i-1×ln(1-T_r) , where the summation is from i = 2 to nTerms -1

  T_r = T/T_c, T_c is the critical temperature, and s^o = 1 N/m
