Baker-Swerdloff Dead-Oil Gas-Oil Interfacial Tension Calculator

σod=σ68+(T−68)(σ100−σ68)100−68\sigma_{od}=\sigma_{68}+\frac{(T-68)(\sigma_{100}-\sigma_{68})}{100-68}

Enter the required inputs, confirm the units, and run the calculator to solve sigma_od. Review the formula source and assumptions before using the result in engineering work.
