I teach Process Equipment Design and use Coulson & Richardson’s Chemical Engineering Series, 4th Ed., vol 6 by R.K.Sinnott as one of the textbooks.
One of my students is very keen to comment that the solution to Example 12.2 in the textbook (pp 679-683 – example of shell-and-tube HE design) maybe incorrect. And I agreed.
As stated in Example 12.2, the pressure drop for each stream is limited to 100 kN/m2.
Meanwhile the calculated pressure drop for the shell-side is 252 kN/m2. Still, it is concluded that 252 is “well within the specification”.
Can anyone add any comment on this?
Lots of books have typos this one probably should have been 1000 instead of 100. I don't have the book so I can't check if there is something more subtle but a limit of 100 kN/M2 (about 14.5 psi) seems very low to me
I don't know about that example but, based on my experience the che. eng. vol. series by Coulson & Richardson have many errors even in calculation of molecular weight , but they are wrote in way easy to understand
