A sheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200°C and is permitted to achieve a steady-state diffusion condition. The diffusion coefficient for nitrogen in steel at this temperature is 6 x10-11 m²/s and the diffusion flux is found to be 1.2 x 10-7 kg/m²s. Also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m³. How far into the sheet(in mm) from this high-pressure side will the concentration be 2.0 kg/m³?
