Irrigation in the Pacific Northwest

Drip Line Rate

The drip line application rate is specific to your irrigation system and shouldn't change, so take a note of it. This constant rate is multiplied by all future irrigation set times to give the net application depths for those sets. Use this form to calculate the water application rate of drip irrigation lines (tape, tubing) given the flow rate from individual emitters, a constant spacing of the emitters along the drip line, and a constant spacing between the drip lines. Learn more about the units used on this page.

Spacing between emitters in the tubing or tape:
Distance between drip lines:

The Equation

This calculator uses this equation to determine the Application Rate of a drip line irrigation system.
