Question This question was created from ChBE3210_Su16_HW07 https://www..com/file/22124087/ChBE3210-Su16-HW07/ I’m looking for the answer to part A. I’m pretty sure the assumptions I can make are: 1. no bulk rxn 2. Stagnant medium 3. 1-Dimenisional (x,y,z coord. system) From there, solve for nA from fick’s equation, plug it into gen. dif eqn for mass transfer then solve for rho A. Not sure what this looks like. Also, what are the boundary conditions? ATTACHMENT PREVIEW Download attachment 22124087-323507.jpeg 3) L Water (Quiescent) Salt An engineer decides to set up a solar pond by first covering the bottom of a reservoir with a solid layer of salt and then adding fresh water to a depth L = 1.0 m at time t = 0. Diffusion of the salt into the fresh water will then generate the necessary salinity gradient. The salt is NaCl, which has a diffusivity in water of D = 1.2.10-9 m /s at 30 C and saturation density in water praCI, sat = 400 kg/m3. As a first approximation, it can be assumed that the diffusion coefficient and the total mass density in the solution, pot, are constant. Note that the assumption of constant total density implies that a certain mass of salt is replaced by an equal mass of water during dissolution. A/ Starting from Fick’s rate equation and the general differential equation for mass transfer, derive the differential equation for mass density of NaCl in the solar pond, pNacl. Clearly state your assumptions in order to receive full credit! B/ Provide the initial and/or boundary conditions needed to solve the differential equation for the early stages of the salt dissolution process.
