Drip Irrigation Sizing

Size emitters, sector flow and daily operating time against available capacity.
USER INPUT

Calculation inputs

Saved locally

Empty fields are never replaced with invented agronomic values. Results update only from visible data.

METHOD / TRACEABILITY

Visible formulas and assumptions

Qtotal = Nplants × Ngoutteurs/plant × qgoutteur | durée = volume journalier ÷ Qtotal
  • The duration per sector delivers each block its share of daily volume.
  • No pipe diameter is inferred from these inputs alone.

Drip Irrigation Flow & Runtime Calculator

Size emitter, row, sector and system flow, then calculate runtime against the crop water requirement.

Calculation method

Emitter count and nominal discharge determine total flow. Sectoring divides simultaneous demand; daily water volume divided by sector flow determines runtime.

Formulas used

  • Total flow = plants × emitters/plant × emitter flow
  • Sector flow = total flow / sectors
  • Runtime = required volume / sector flow

Worked example

1,000 plants with two 4 L/h emitters require 8 m³/h if all operate simultaneously.

How to interpret the result

Compare sector flow with available source flow and check that total daily runtime fits the available operating window.

Common mistakes

  • Using nominal emitter flow at an unverified pressure.
  • Confusing runtime per sector with total system runtime.
  • Ignoring filtration and uniformity.

Scope and limitations

  • Hydraulic uniformity and lateral pressure variation require a detailed network design.

Frequently asked questions

Why divide the field into sectors?

Sectoring keeps simultaneous flow within source, pump and pipe capacity.

Is nominal emitter flow always achieved?

No; actual discharge depends on pressure, emitter type, clogging and manufacturing variation.

Does this size pipe diameters?

No. It establishes design flow; pressure-loss and uniformity checks remain necessary.
