Assuming \(Re = 100\) and \(Sc = 1\) :

A mixture of two gases, A and B, is separated by a membrane that is permeable to gas A but not to gas B. The partial pressure of gas A on one side of the membrane is 2 atm, and on the other side, it is 1 atm. If the membrane thickness is 0.1 mm and the permeability of the membrane to gas A is 10^(-6) mol/m²·s·atm, calculate the molar flux of gas A through the membrane. Mass Transfer B K Dutta Solutions

\[k_c = rac{10^{-5} m²/s}{1 imes 10^{-3} m} ot 2 ot (1 + 0.3 ot 100^{1/2} ot 1^{1/3}) = 0.22 m/s\] Assuming \(Re = 100\) and \(Sc = 1\)
