Consider a steel tank containing hydrogen at 10 atm pressure with a vacuum on the outside. Take the solubility of hydrogen in steel at the inner surface in equilibrium with hydrogen at 10 atm to be 10-2 g/cm3 and the diffusion coefficient for hydrogen to be 10-5 cm2/sec. Calculate the flux of hydrogen through a wall of thickness 1 mm, in grams per square centimeter per second.
