Critical pressure Cavett relation
Input(s)
\(T_{b}\): Boiling Point Temperature \(\left({ }^{\circ} \mathrm{F}\right)\)
API: API Gravity of oil (API)
Output(s)
\(P_{c}\): Critical Pressure (Psi)
Formula(s)
\[
\begin{aligned}
\mathrm{P}_{\mathrm{c}}= & 10^{(2.829)}+\left(0.0009112 * \mathrm{~T}_{\mathrm{b}}\right)-\left(0.0000030175 * \mathrm{~T}_{\mathrm{b}}^{2}\right)+\left(0.0000000015141 * \mathrm{~T}_{\mathrm{b}}^{3}\right)-\left(0.000020876 * \mathrm{~T}_{\mathrm{b}} * \mathrm{API}\right) \\
& +\left(0.000000011048 * \mathrm{~T}_{\mathrm{b}}^{2} * \mathrm{API}\right)+\left(0.0000000001395 * \mathrm{~T}_{\mathrm{b}}\right)^{2} * \mathrm{~A}
\end{aligned}
