‘Graphical’ Evaluation to Calculate the Number of Transfer Units – Solution

Solve the Problem:

Calculate the number of transfer units (Nog)

Run the program and let’s see what the output shows.  It will show up in your IPython window.

Number of Transfer Units based on Gas Phase Resistance

Number of Transfer Units based on Gas Phase Resistance

The answer we get is NOG = 3.52 transfer units.  Henley and Seader got 3.44 transfer units (obtained graphically) and Rosen and Adams calculated 3.73 units (with a spreadsheet).  So, essentially, we all got the same answer within the error of the data and the different methods.  I show the array values so you can compare with Rosen and Adams if you want (and have the article, get it, it’s a good one.)  We like short and sweet, let’s proceed to another problem.  Ciao!
