Precipitation Rate Calculator

Use the Precipitation Rate Calculator tool to input your desired application rate and sprinkler spacing.

Enter your desired application rate in inches or millimeters per hour. Next, enter your desired spacing between sprinklers and your desired spacing between laterals in feet or meters.

The Precipitation Rate Calculator will tell you what flow rate you need. You can use this information to help you select a sprinkler that provides that flow.  You can also determine the nozzle size you need based on your system pressure.
