Drip Tip - Calculating Application Rates for XF Dripline

The application rate is the rate that XF Series Dripline applies water to the soil. This is used to determine run times for the zone based on the plant watering requirements. The Application Rate Table is provided to make it easy to determine application rates for every model of XF Series Dripline when using common row spacing (12”-24” / 30cm-61cm).   Additional calculations are provided on the second and third page, broken out my measurement system, to help you determine application rate, total flow rate and how much dripline you will need.

Using the Application Rate Table

The table is divided into two sections, a 0.6 GPH (2.3 l/hr) emitter flow section and a 0.9 GPH (3.4 l/hr) emitter flow section. Go to the section for the specified emitter flow rate and find in the left hand column the specified emitter spacing. Now, find the lateral row spacing across the top of the table. Follow the lateral row spacing column down and the emitter spacing row across until the two meet. This is the application rate in inches per hour (centimeters per hour).

For example, a 0.6 GPH (2.3 l/hr) emitter flow rate with 18” (46 cm) lateral row spacing and 18” (46 cm) emitter spacing has an application rate of 0.43 (1.09 cm/hr) inches per hour.
