| 7.1-1. |
Unsteady-State Diffusion in a Thick Slab. Repeat Example 7.1-2 but use a distribution coefficient K = 0.50 instead of 2.0. Plot the data. |
| A1: | Ans. c = ci = 5.75 × 10−2 (x = 0), c = 2.78 × 10−2 (x = 0.01 m), cLi = 2.87 × 10−2 kg mol/m3 |
| 7.1-2. |
Plot of Concentration Profile in Unsteady-State Diffusion. Using the same conditions as in Example 7.1-2, calculate the concentration at the points x = 0, 0.005, 0.01, 0.015, and 0.02 m from the surface. Also calculate cLi in the liquid at the interface. Plot the concentrations in a manner similar to Fig. 7.1-3b, showing interface concentrations. |
| 7.1-3. | Unsteady-State Diffusion in Several Directions. Use the same conditions as in Example 7.1-1 except that the solid is a rectangular block 10.16 ... |
