When a-iron is subjected to an atmosphere of nitrogen gas, the concentration of nitrogen in the iron, CN (in weight percent), is a function of hydrogen pressure, pN2 (in MPa), and absolute temperature (T) according to CN = 4.90 * 10-31pN2 expa - 37,600 J>mol RT b (5.14) Furthermore, the values of D0 and Qd for this diffu- sion system are 5.0 107 m2 /s and 77,000 J/mol, re- spectively. Consider a thin iron membrane 1.5-mm thick at 300C. Compute the diffusion flux through this membrane if the nitrogen pressure on one side of the membrane is 0.10 MPa (0.99 atm) and on the other side is 5.0 MPa (49.3 atm).
