Estimate the steady-state flux of atomic hydrogen at 25 °c through a steel vessel of wall thickness 4 mm given that its inside surface is kept saturated with hydrogen at a concentration of 4.2 moles m; the outside surface is exposed to the atmosphere. the diffusivity of hydrogen 2 -1 in α-iron 1s if the vessel contains 20 moles of hydrogen, estimate the hours taken to dissipate all of the hydrogen given that the vessel has a surface area of 2m comment on why it is possible to store hydrogen gas in iron cylinders for much longer periods how does dissolved hydrogen affect the mechanical properties of a-iron?
