I'd like to find out the basis of the following formulas used throughout the world (i.e. how were they developed, was field data used to verify and what range of populations/flows are they more valid for). Any input/experience with these formulas is most appreciated.</P><P>1. Ten States</P><P>2. US Air Force</P><P>3. Babbitt</P><P>4. Harmon</P><P>5.
