A thin sheet of Iron is in contact with a carburizing gas on one side and a decarburizing gas on the other at 1000C a. Sketch the resultant carbon concentration profile when a steady state has been reached assuming surface concentration are maintained at 0.15 and 1.4 wt% C b. If Dc increases from 2.5 x 10 -11 m2 s-1 at 0.15% C to 7.7 x 10 -11 m2 s-1 at 1.4%C, what will be the quantitative relationship between the concentration gradients at the surfaces

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
