Saturated vapor pressure

Values for calculation

$T$ $\mathrm{°C}$

Calculation

Transformed temperature

$$θ=\left(\left(T+273.15\right)+\cfrac{-0.23855557567849}{\left(T+273.15\right)-0.65017534844798\cdot10^3}\right)$$

Function $ A $

$$A=θ^2+0.11670521452767\cdot10^4\cdot θ-0.72421316703206\cdot10^6$$

Function $ B $

$$B=-0.17073846940092\cdot10^2\cdot θ^2+0.12020824702470\cdot10^5\cdot θ-0.32325550322333\cdot10^7$$

Function $ C $

$$C=0.14915108613530\cdot10^2\cdot θ^2+\left(-0.48232657361591\cdot10^4\cdot θ\right)+0.40511340542057\cdot10^6$$

Saturated vapor pressure

$\text{if }\ \left(T+273.15\right)\le 623.15$
$$P_{SV}=1\cdot10^6\cdot\left(\cfrac{2\cdot C}{-B+\sqrt{B^2-4\cdot A\cdot C}}\right)^4$$
$\text{else}$
$$P_{SV}=1\cdot10^6\cdot (0.34805185628969\cdot10^3+\left(-0.11671859879975\cdot10^1\cdot \left(T+273.15\right)\right)+0.10192970039326\cdot10^{-2}\cdot \left(T+273.15\right)^2)$$
