- A Sheet Of Steel 5 0 Mm Thick Has Nitrogen Atmospheres On Both Sides At 900 C And Is Permitted To Achieve A Steady State 1 (50.76 KiB) Viewed 39 times
A sheet of steel 5.0 mm thick has nitrogen atmospheres on both sides at 900∘C and is permitted to achieve a steady-state diffusion condition. The diffusion coefficient for nitrogen in steel at this temperature is 46.70 m2/s and the diffusion flux is found to be 53.81 kg/m2.s. Also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 39.52 kg/m3. How far into the sheet (in mm ) from this highpressure side will the concentration be 29.12 kg/m3 ? Assume a linear concentration profile.
