Asheet of bcc iron 4.6-mm thick was exposed to a carburizing atmosphere on one side and a decarburizing atmosphere on the other side at 725°c. after having reached steady state, the iron was quickly cooled to room temperature. the carbon concentrations at the two surfaces were determined to be 0.010 and 0.0063 wt%. calculate the diffusion coefficient if the diffusion flux is 3.7 × 10-8 kg/m2-s, given that the densities of carbon and iron are 2.25 and 7.87 g/cm3, respectively.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
