Can anyone please suggest a formula to calculate the diffusion coefficient of water vapor in a gas mixture of N2, CO2 ,O2, and H2O at 1 atm and 0 to 200 °C.
I found this formula.
D'A = (1 - YA)/(YB/DAB + YC /DAC + ..)
where D'A is the diffusion coefficient of the component A in the mixture with B, C, ..., YA, YB, YC are the molar fractions of the appropriate components; and DAB and DAC are the diffusion coefficients in the AB and AC binary systems, respectively.
But to use that I need experimental data of the diffusion coefficient of water vapor at pure N2, O2 and CO2.
Can anyone please mention a reliable source to get the experimental values or mention another theoretical equation to derive a formula ?
