Gaseous hydrogen at 150 psia and 80°F is stored in a small, spherical, steel pressure vessel having an inside diameter of 4 in. and a wall thickness of 0.125 in. At these conditions, the solubility of hydrogen in steel is 0.094 lbmol/ft3 and the diffusivity of hydrogen in steel is 3.0 x 10-9 cm2/s. If the inner surface of the vessel remains saturated at the existing hydrogen pressure and the hydrogen partial pressure at the outer surface is assumed to be zero, estimate:

(a) The initial rate of mass transfer of hydrogen through the metal wall

(b) The initial rate of pressure decrease inside the vessel
