A sheet of steel 5.0-mm thick has nitrogen atmospheres on both sides at 1000°C and is permitted to achieve a steady-state diffusion condition. The diffusion coefficient for nitrogen in steel at this temperature is 1.95 × 10-10 m2 /s, and the diffusion flux is found to be 1.2 × 10-7 kg/m2.s. Also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 3 kg/m3 . How far into the sheet from this high-pressure side will the concentration be 0.5 kg/m3 ? Assume a linear concentration profile
