Concentric reduction losses.

Hi, I´m starting to design a sprinkler system, the thing is.. about the minor losses (concentric and tee reductions) to be considered on the hydraulics calculations.


For example, I have a 6" main that gets reduced to 4" and then to 2 1/2" at the end. Is  recommended to include the losses for the reductions involved on those pipes?.


And on the other hand, every 3 meters from the main pipe it comes out a 1 1/2" pipe (from a weldolet and yes, even from the 6" pipe) that feeds the sprinkler. Do I need to include the "reduction loss from a 6" to 1 1/2" pipe" in the calculations??.
