Irrigation Tutorials[hdpe]This is called friction loss in the irrigation industry (although the pressure loss comes from more than just friction.) So the size of pipe you use to supply the sprinkler head with water must not only supply the right amount of water, it must also not reduce the pressure below the amount needed to operate the sprinkler efficiently.

Oct 25, 2017 Water supply should be limited to about 4 gallons per minute (gpm) for ½ pipe, 8 gpm for ¾ and 12 gpm for 1 pipe to keep friction loss at an acceptable level. You may need to add new nozzles, replace worn nozzles or change to closer spacing to get greater uniformity of overhead systems.[price]Head and pressure in pumps Water Tech Online[hdpe]Back in the mid 1960s, I was employed as an apprentice mechanic in a Birmingham, AL, steel mill.
