Extrapolation of binary diffusivity to a very high temperature, a value of DAB = 0.151 cm 2
Question:
Extrapolation of binary diffusivity to a very high temperature, a value of DAB = 0.151 cm2/s has been reported1 for the system CO2-air at 293K and 1 atm. Extrapolate DAB to 1500K by the following methods:
(a) Equation 17.2-1.
(b) Equation 17.3-10.
(c) Equations 17.3-12 and 15, with Table E.2,
What do you conclude from comparing these results with the experimental value 1 of 2.45cm2/s?
