Adifferential nitrogen pressure exists across a 2-mm-thick steel furnace wall. after some time, steady-state diffusion of the nitrogen is established across the wall. given that the nitrogen concentration on the high-pressure surface of the wall is 2 kg/m3 and on the low-pressure surface is 0.2 kg/m3, calculate the flow of nitrogen through the wall (in kg/m2⋅h) if the diffusion coefficient for nitrogen in this steel is 1.0 × 10-10 m2/s at the furnace operating temperature.
