Consider a thin iron membrane with the thickness and temperature listed below. Calculate the flux in (kg/(m2-s)) through this membrane if the hydrogen pressure on one side of the membrane is 0.17 MPa, and on the other side it is 6.1MPa, utilizing the densities provided by your examination booklet. Assume the values for D0 is 4.9x10-7 m2/s and Qd is 13.4KJ/mol.
