Abstract:
When gas A is dry air and mixed with an oxygen-free dry gas or gas mixture B (e.g., N_{2}), then the p_{O2} in water equilibrated with this gas mixture is
p_{O2} = (p_{b}βp_{H2O,Ts})ΓΟ_{A}ΓΟ^{β}_{o2}, (1)
where p_{b} is barometric pressure [kPa], p_{H2O,Ts is the saturation water vapor pressure at the temperature of the water sample, Ξ¦A is the volume fraction of gas A in the gas mixture leaving the gas mixing pump, }
Ο_{A}=p_{A}/p_{b} and 1βΟ_{A}=p_{B}/p_{b}, (2)
Ο^{β}_{o2} is the volume fraction of oxygen in dry air which can be taken as constant Ο^{β}_{o2}=0.20946.
