(35 points) Consider a 1-mm thick α-iron (BCC) membrane subjected to a temperature of 250°C. The membrane is also subjected to pressure sides as shown below. Compute the diffusion flux through this membrane if the hydrogen pressure on one side of the membrane is 0.15 MPa (1.48 atm), and on the other side 7.5 MPa (74 atm). When a small enough α-iron (BCC) plate is subjected to an atmosphere of hydrogen gas, the concentration and mass quantities of hydrogen in sides A and B are given below: Low-pressure side A: C(H)(A) = 7.02 x 10^(-5) wt% m(H)(A) = 7.02 x 10^(-5) Kg in 100g of α-Fe P(A) = 7.5 MPa High-pressure side B: Pure α-Fe C(H)(B) = 9.93 x 10^(-6) wt% m(H)(B) = 9.93 x 10^(-6) Kg in 100g of α-Fe P(B) = 0.15 MPa ρ(Fe) = 7.87 (g)/(cm^3) α-Fe in a hydrogen atmosphere 2.1 The volume of Fe in gas A in 100g is: a. V(Fe(A)) = 4.27 x 10^(-5) m^3 b. V(Fe(A)) = 3.27 x 10^(-5) m^3 c. V(Fe(A)) = 5.27 x 10^(-5) m^3 d. None of the above 2.2 The volume of Fe in gas B in 100g is: a. V(Fe(B)) = 1.27 x 10^(-5) m^3 b.

C(H(A))'' = 5.53 x 10^(-3) Kg/(m^3) b. C(H(A))'' = 3.51 x 10^(-4) Kg/(m^3) c. C''H(A) = 5.27 x 10^(-5) Kg/(m^3) d. None of the above 2.4 The concentration of hydrogen at the A face in kilograms of H per cubic meter of alloy is: a. C(H(B))'' = 4.87 x 10^(-5) Kg/(m^3) b. C(H(B))'' = 7.82 x 10^(-4) m^3 c. C''H(B) = 6.65 x 10^(-3) Kg/(m^3) d.
