I am completing some research on various methods for computing sewer peak factors for assessing impacts on existing sewer and designing new sewers.  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.

1.  Ten States

2.  US Air Force

3.  Babbitt

4.  Harmon

5.  Sydney Water
