When A Iron Is Subjected To An Atmosphere Of Hydrogen Gas The Concentration Of Hydrogen In The Iron C In Weight Per 2 (17.55 KiB) Viewed 49 times
When a-iron is subjected to an atmosphere of hydrogen gas, the concentration of hydrogen in the iron, C₁, (in weight percent), is a function of hydrogen pressure, PH, (in MPa), and absolute temperature (T) according to CH= 1.34 x 10-2√√PH, exp(- Furthermore, the values of Do and Q for this diffusion system are 4.8 x 107 m²/s and 11 kJ/mol, respectively. Consider a thin iron membrane 2.7-mm thick that is at 227°C. Calculate the diffusion flux [in kg/(m²-s)] through this membrane if the hydrogen pressure on one side of the membrane is 0.16 MPa, and on the other side 7.0 MPa, given that the density of iron is 7.87 g/cm³. 27.2 kJ/mol RT
Part 2 (a) What is the concentration of hydrogen at the B face in kilograms of H per cubic meter? C'H(B) = kg/m³ (b) What is the concentration of hydrogen at the A face in kilograms of H per cubic meter? C'H(A) = kg/m³
