2. A thick, impermeable pipe 3cm in diameter and 10cm long contains a gas that includes 0.51020 Nitrogen atoms per cm3 and 0.51020 Hydrogen atoms per cm3 on left side of an iron membrane. Gas is continuously introduced to the pipe to assure a constant concentration of Nitrogen and Hydrogen. The gas on the right side of the membrane includes a constant 1018N atoms per cm3 and 1018H atoms per cm3. The entire system is to operate at 700C(973k). Membrane iron has a BCC structure. Determine the minimum and maximum thicknesses (x= ?) of the iron membrane that will allow no more than 1% of the Nitrogen to be lost through the membrane each hour while allowing 90% of the Hydrogen to pass through the membrane per hour. Hint: Use Fick's First Law
