Gas/Water Interfacial Tension

Gas/Water Interfacial Tension correlation was published by Baker and Swerdloff in 1956.

Math and Physics

\sigma_{74} =75 - 1.108P^{0.349}
\sigma_{280} =53-0.1048P^{0.637}
At\ T<74F,\ \sigma_w=\sigma_{74}
At\ 74F<T<280F,\ \sigma_w=\frac{\sigma_{74} + (T - 74) * (\sigma_{280} - \sigma_{74})}{ (280 - 74)}
At\ T>280F,\ \sigma_w=\sigma_{280}

Nomenclature

P = pressure, psia
\sigma_w = gas/water interfacial tension, dynes/cm
T = temperature, °F
