That said, the severity of the bend is the restriction. If a 90 degree bend happens over 4 inches, then the restriction is less than a fitting that accomplishes the same thing in half an inch. The same thing that happens while driving. You can take a curving 90 at lot faster than you can take an sharp 90.
