Compute a value for DAB for a system of argon (A) and oxygen (B) at 294 K and atmospheric pressure.

DAB = 1.921 E-5 m²/s

Explanation:

DAB = ((1 E-7 T∧ (1.75)) * ((1/MA + 1/MB) ∧ (1/2))) / [ P * (∑vA) ∧ (1/3) + (∑vB) ∧ (1/3) ]² ... Fuller et All.

∴ ∑vA = 16.1 m³/Kg ... from literature

∴ ∑vB = 16.6 m³/Kg ... from literature

∴ T = 294 K

∴ P = 1 atm

∴ MA = 39.948 Kg/Kmol

∴ MB = 32 Kg/Kmol

⇒ DAB = ((2.087 E-3) * (0.2372)) / [1 * (25.766) ]

⇒ DAB = 1.921 E-5 m²/s
