During the non-steady state diffusion of nitrogen in a semi-infinite bar of steel, it is found that it takes 5 hours to reach a concentration of 1.38 wt% nitrogen at a depth of 1.0 mm. How much time would it take to reach the same concentration of nitrogen at a depth of 2.0 mm assuming the same surface and initial concentrations. Co = 1.38 wt%, Given T = 800 °C, D = 2.22 x 10-10 m?s-1, Cor = Owt%, Cs...
