Chapter 12: Steady-State Nonisothermal Reactor Design: Flow Reactors with Heat Exchange

Side Note

In Barkelew's orginial article he gives an example calculation. The approximation is in calculating S:

If only A and inerts enter and the mole fraction, yA0, of A is 0.1, then QI = 0.9/0.1=9.

Further, the author assumes

Another way to get the same result is if

There is also an error in the article in calculating (-rA0). The author forgot to multiply k by yA0. (i.e., -rA0=kyA0).
