A sheet of steel 1.5mm thick has nitrogenatmospheres on both sides and ispermitted to achieve a steady-statediffusion condition. The diffusioncoefficient for nitrogen in steel a is 6.05E-11 m2/s, and the diffusion flux is found tobe 1.5E-7kg/m? s. Also, it is known that theconcentration of nitrogen in the steel atthe high concentration is 4.97 kg/m3 whilethe lower concentration is 2.5 kg/m3 . Howfar XA (mm) will be from the sheet to reachthe lower concentration?XA =mm

Given that thickness = 1.5 mm DAB = 6.05 X 10-11m2s JA = 1.5 x 10-7kgm2sCA = 4.97CB = 2.5 kg/m3

Countercurrent diffusion across a vapor film.An insulated glass tube and condenser are mounted on a reboiler containing benzene and toluene. The condenser returns liquid reflux down the wall of the tube. At one point in the tube, the temperature is 170oF, the vapor contains 30 mol% toluene, and the reflux contains 40 mol% toluene. The thickness of the stagnant vapor film is estimated to be 0.1 in. The molar latent heats of benzene and toluene are equal. Calculate the rate at which toluene and benzene are being interchanged by equimolar countercurrent diffusion at this point in the tube in lbmol/h-ft2, assuming that the rate is controlled by mass transfer in the vapor phase.Gas diffusivity of toluene in benzene = 0.2 ft2/h. Pressure = 1atm (in the tube). Vapor pressure of toluene at 170oF =400 torr.

A sheet of steel with 100cm2 area has nitrogen(N2) atmospheres on both sides and is permitted to achieve a steady-state diffusion condition. In order to increase the flow rate of N2, which of the following modifications is useful? Steel sheet O Increase the N2 pressure at C1 O Decrease the temperature.

In this type of Fickian diffusion, the diffusing species is moving through a "stagnant" bed of another species in solution. -Unsteady-state Diffusion -None of the choices -Unimolecular Diffusion -Knudsen Diffusion -Equimolar Counter Diffusion
A differential nitrogen pressure exists across a 2-mm thick steel furnace wall. After some time, steady-state diffusion of the nitrogen is established through the wall. Given that the nitrogen concentration on the high-pressure surface of the wall is 2kg/m^3 and on the low-pressure surface is 0.2kg/m^3, calculate the steady-state flow of nitrogen through the wall if the diffusion coefficient for nitrogen in this steel is D=1.0×10^-10 m^2/s at the furnace operating temperature. Your answer should be in units of g/m^2*h.
1) A biofilm is a layer-like aggregation of microscopic animals, plant or bacteria attached to a solid surface. Assume such a biofilm where the reactant is consumed Bulk fluid only at the solid surface, maintaining a particular value of surface concentration. Calculate the steady-state reactant flux into a biofilm of thickness 0.01 cm, if the diffusivity of the reactant in the biofilm is 0.8 cm²/day. Assume the reactant concentration in the bulk fluid to be uniform at 3.2 mg/liter. At the surface, reactant concentration is 0.25 mg/liter. Biofilm Surface
Consider a diffusion process in a semi-infinite solid with a source at x=0 mm, the concentration of the diffusing species is 2 nm-3 at x=5 mm and t=1 hr (since the start of the process). At what time the concentration at x=15 mm will reach 3 nm-3 ?
A new type of porous material serves as food packaging film, as shown in the figure below. The film rests on a nonporous metal plate. The packaging film is 0.20 cm thick (2.0 mm). The food contains liquid water, which exerts a vapor pressure of 0.030 atm at 25Â°C. At 25Â°C, the effective diffusion coefficient of water vapor in the porous film is 1.3 x 10^-4 cm/s, and the molecular diffusion coefficient of water vapor in air is 0.26 cm/s. You may assume that the total system pressure is constant at 1.0 atm, and initially, the gas space of the porous film contains air and no water vapor. How long will it take for the water vapor to achieve a partial pressure of 0.0150 atm at the back surface of the film (z = 0) at 25Â°C?
