So if the pressure in is 50 psi in a .028 in3 line (3/16" ID), the pressure does NOT drop between the first and second set of holes? How about if the first hole is .028"? The line after that has the same pressure as the hole, and equal to 50% of the line in.
The delivery rate is a function of the hole area X the square root of the pressure differential.
I think you misunderstand what's being said here - although (my bad) I did leave out the word "combined" thinking people would be smart enough to assume that!:
" the "combined" area of the
holes is equal to or smaller than the feed line they will all squirt the same amount (or pretty damn close to it)."
