Weakly ask Antoine, the lead developer
Thread Content
I have a minor question: what does ΔT/K mean in the Antoine equation in the appendix of \"Thermodynamics of Chemical Engineering\"? Is it within the suitable temperature range for use? However, the pressure value calculated by substituting H2O into this equation at 300 degrees is also correct according to the Antoine equation for water (280–441 K)
It should be Kelvin temperature. That cannot be considered pressure; it is the saturated vapor pressure. If it is a pure component, then it is pressure.
Possible temperature range, with instructions from Antoine
Look at the unit; the range of use is Kelvin; the unit to be entered is Celsius
