Critical temperature Cavett method
Input(s)
\(T_{b}\): Boiling Point Temperature \(\left({ }^{\circ} \mathrm{F}\right)\)
API: API Gravity (API)
Output(s)
\(T_{c}\): Critical Temperature \(\left({ }^{\circ} \mathrm{F}\right)\)
Formula(s)
\[
\begin{aligned}
\mathrm{T}_{\mathrm{c}}= & 768.071+1.7134 * \mathrm{~T}_{\mathrm{b}}-\left(0.0010834 * \mathrm{~T}_{\mathrm{b}}^{2}\right)+\left(0.0000003889 * \mathrm{~T}_{\mathrm{b}}^{3}\right)-\left(0.00089213 * \mathrm{~T}_{\mathrm{b}} * \mathrm{API}\right) \\
& +\left(0.00000053095 * \mathrm{~T}_{\mathrm{b}}^{2} * \mathrm{API}\right)+\left(0.000000032712 * \mathrm{~T}_{\mathrm{b}}^{2} * \mathrm{API}^{2}\right)
\end{aligned}
