I have the GPM rate for all nozzles in my zones as well as data from catch cups.
How do I use this data to correctly enter 1. nozzle types, 2. efficiency and 3. area so it accurately calculates water usage?
For example, one of my zones is as follows:
I have 6 nozzles with a combined output of 14.5gpm.
Total area is 133.97 m2
Cup data in ml with a 16.25in coverage area: 38 25 40 31 35 48 50 41 28 27 32 42 which averages 20.84mm/hour. Is this calculation correct? https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=36.4166ml%2F16.25+square+inch with a 10 minute runtime so multiply by 6.
Right now I just made a custom nozzle for 20.84mm/hour and set the efficiency to 100%, but I know that’s not going to calculate runtimes very well and water usage is not accurate as some of the water gets sprayed outside of the “total area”.
This seems way more complicated than it should be!
