Irrigation Total with Custom Nozzle

[franz]

Here is a little more info on the topic.

Fixed spray head

Our nozzle types use precipitation in./hr which can be calculated using a catch cup test or knowing your gallons per minute, or by picking the closest nozzle type (we use industry standard defaults for in./hr). If you use a catch cup test it will tell you precip in./hr as well as efficiency which measures all of your heads application (efficiency takes into account overlapping heads, 360 vs 180, etc.) Catch cup instructions Qucik and dirty http://www.sprinklerwarehouse.com/DIY-Calculating-…

If you do know GPM, this is an easy way to derive precip in./hr (I would just use the iOS app)

Efficiency can only be calculated using a catch cup test. Plenty of information above on the topic, but it will take some more time to get that data.

Hope this helps.
