Hi,all.
a book(j.p holman,heat transfer 7e,chapter 11) gives
C (subindex)A = (ro) subindex A= P subindex A x M subindex A / Ro(universal) T
but another book(stanley middleman,an introduction to mass and heat transfer) gives
Ci=(ro)i/Mi. these are very different from each other.Ci is total molar concentration of
that species and ro is density that is mass concentration to be used in Fick's law.which one is true?
