Estimate flow from drip tape emitters per length.
Counting the emitters along a length of drip tape and multiplying by each emitter's flow gives the total delivery in gallons per hour. Knowing the flow rate sizes the pump and filter and lets you time irrigation so crops get the right amount without runoff.
Drip Tape Flow
Emitters = tape length x 12 ÷ spacing; flow = emitters x emitter gph
Emitters = tape length x 12 ÷ spacing; flow = emitters x emitter gph Counting the emitters along a length of drip tape and multiplying by each emitter's flow gives the total delivery in gallons per hour.
Knowing the flow rate sizes the pump and filter and lets you time irrigation so crops get the right amount without runoff.
This calculator takes 3 inputs: Tape length, Emitter spacing, Emitter flow. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
