Input(s)

TbT_{b}: Boiling Point Temperature (F)\left({ }^{\circ} \mathrm{F}\right)

API: API Gravity (API)

Output(s)

TcT_{c}: Critical Temperature (F)\left({ }^{\circ} \mathrm{F}\right)

Formula(s)

Tc=768.071+1.7134 Tb(0.0010834 Tb2)+(0.0000003889 Tb3)(0.00089213 TbAPI)+(0.00000053095 Tb2API)+(0.000000032712 Tb2API2)\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}
