Precipitation Rate Formula
GPM (Full Circle Head) X 96.3
-------------- = PR
Head Spacing X Row Spacing (Divide)


Precipitation Rate for Drip
GPH (one emitter) X 231
------------ = PR
Head Spacing (inches) X Row Spacing (inches)


Runtime Formula

I x 60
RT ----=Runtime
PR


Calculating Drip Flow Zone

Total Linear feet of drip /emitter spacing x GPH of emitter/ 60 = GPM for that zone
