L A B D Two containers (A and B) are connected using a pipe (length:L=20cm, diameter: D). Both A and B are filled with stagnant acetic acid aqueous solution. In container A, acetic acid concentration is 2.0 mol/L. In container B, acetic acid concentration is 0.1 mol/L. The whole system is at the same temperature and pressure. (20 pt) The diffusivity parameters of acetic acid in waters Table 1: Diffusivity of acetic acid in water Solute(1) Solvent (2) TOC Diffusivity Di2 (m/s(10")) acetic acid water 10 0.77 acetic acid 25 1.26 water Assuming the system is at steady state. Calcualte: 1. What is the flux of acetic acid in the pipe for the system temperature T=10"C and T25 "C? (5 pt) 2. If you want to control the total diffusive mass transfer rate from A to B less than 3.4x10 mol/hir at 25C, what is the maximum pipe diameter you should choose for this process? (5 pt)
