After completing this chapter, you will be able to:
Develop differential models for problems in mass transfer where the concentration varies along only one spatial dimension.
Derive differential equations for the species concentration by use of the conservation law followed by Fick’s law in Cartesian coordinates.
Derive the model equations in cylindrical and spherical coordinates and understand the differences arising due to geometry.
State the equation in vector form and be able to use it in any coordinate system.
Solve some simpler problems, especially those involving mass transfer with reaction, and examine the property of the solution.
This chapter illustrates the ...
