A sheet of steel 4.4 mm thick has nitrogen atmospheres on both sides at 1200C and is permitted to achieve a steady-state diffusion condition. The diffusion coefficient for nitrogen in steel at this temperature is 5.6x10-11 m2/s, and the diffusion flux is found to be 4.7 x 107 kg/m2.s. Also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4.7 kg/m. How far into the sheet from this high-pressure side will the concentration be 2.1 kg/m3? Assume a linear concentration profile. O 0.13 mm O 0.31 mm O 0.65 mm O None of the answer options O 0.82 mm Step by Step Solution
