Hydrogen gas at 25 degree Celcius and 2.5 atmosphere flows through a rubber tubing of 12 mm inside radius and 24 mm outside radius. The binary diffusion coefficient of hydrogen is 2.1 x 10-8 m2/s and the solubility of hydrogen is 0.055 m3 of hydrogen per m3 of rubber at 1 atmosphere. If the molecular mass for hydrogen gas is taken as 1.9986 gm/mol, and the concentration of hydrogen at the outer surface of tubing is negligible, calculate the diffusion flux rate of hydrogen per meter length of rubber tubing.

Question
Hydrogen gas at 25 degree Celcius and 2.5 atmosphere flows through a
rubber tubing of 12 mm inside radius and 24 mm outside radius.
The binary diffusion coefficient of hydrogen is 2.1 x 10-8 m2/s
and the solubility of hydrogen is 0.055 m3 of hydrogen per m3 of
rubber at 1 atmosphere. If the molecular mass for hydrogen gas
is taken as 1.9986 gm/mol, and the concentration of hydrogen
at the outer surface of tubing is negligible, calculate the
diffusion flux rate of hydrogen per meter length of rubber
tubing.
