Question

Q) Using the relationship that contaminant flux in the x-direction can be determined as

Jx (g/cm2 – sec) = - Dx(dC/dx) answer the following questions:

a.How would you convert this relationship to a mass flow Ṁx = dMx/dt (g/sec).

b.If you wanted to make Ṁx as small as possible to protect the environment, use your knowledge of the mass flow equation, and of Fick’s Law and of molecular diffusion correlations and list five engineering modifications you could make to the system to achieve your goal.
