Q1 A thin sheet of iron is exposed to a carburizing atmosphere on one side and a decarburizing atmosphere on the other side at 700C. If a condition of steady rate is achieved, compute the diffusion flux of carbon through the plate. The concentration of carbon at positions of 5 mm and 10 mm beneath the carburizing surface are 1.2 kg/m and 0.8 kg/m, respectively. Assume a diffusion coefficient of 3 x 10-11 m/s at this temperature
