FormulaPer zone = Math.floor(supply*(1-reserve/100)/each_flow); Zones = Math.ceil(emitters/Math.floor(supply*(1-reserve/100)/each_flow))

Worked example

Inputs

Emitters
180 emitters
Each flow
2 L/h
Supply
180 L/h
Reserve
20 %

Expected results

Per zone
72 emitters
Zones
3 zones

How to use this tool

  1. Enter the measured quantities and your own planning assumptions.
  2. Review all calculated outputs and the stated limitations.

Try this example

{
  "emitters": 180,
  "each_flow": 2,
  "supply": 180,
  "reserve": 20
}

Accuracy and scope

Flow planning only. Pipe pressure loss, elevation, regulator performance and emitter specifications are not modeled.
