Vapor Pressure of Water calculator Formula:
P = 10A-B/(C+T)
Where:
P: Vapor Pressure of Water
T: Water Temperature, in Celsius
A,B,C: Antoine Constants for Water. When water temperature in the range of 1 - 100 Celsius
A=8.07131, B=1730.63, C= 233.426; when the temperature in the range of 99 - 374 degree Celsius, A=8.14019,
B=1810.94 and C=244.485.
