A capillary has a diameter of 15 m and a length of 0.25 m. In an open system, a gaseous mixture containing hydrogen (A) and nitrogen (B), having a temperature of 358 K is being diffused in the aforementioned capillary. The mole fractions are at a constant value of xA1 = 1.0 and xA2 = 0. Accordingly, for both nitrogen and hydrogen gases, what is the Knudsen diffusivity values if the pressures are given as 0.005, 0.5 and 50 atm. Then calculate the flux with the aforementioned pressures. (R can be used as 82.05710-3 m3 .atm/kgmol.K)
