It has been determined that the steady-state diffusion flux of nitrogen through a steel plate is 1.5 × 10-8 kg/m².s at a temperature of 1300 K (1027°C), and for a concentration gradient of -300 kg/m². What concentration gradient is necessary to give a diffusion flux of 5.0 × 10-8 kg/m².s at 1410 K (1137°C) if the activation energy for diffusion is 124,000 J/mol? AC/Ax = i -350.11 kg/m4 It has been determined that the steady-state diffusion flux of nitrogen through a steel plate is 1.5 × 10-8 kg/m².s at a temperature of 1300 K (1027°C), and for a concentration gradient of -300 kg/m².
