I would recommend you purchase that book. They are
    
not really my 
  
algorithms 
and I don't want to be accused of copyright

reason it 
can't easily be put in a spreadsheet is it is
    
really numerical 
  
calculus and 
the program runs multiple loops (finite steps
    
whereas in calculus 
  
the step 
size is taken to the limit of zero) to develop the
    
performance of a

Hmmm... A search on Amazon says that its not
available.  There's an author that has put a chapter
of his book dealing with duct design online.  I
believe that is Martin Hollman, but I'm at work now
and don't have access to my bookmarks.  Do you have
a pointer to where it can be purchased?
