How this tool works
Estimate runtime using the measured total flow of one zone and a chosen net dose.
time = area × net depth/(η × flow)Example calculation
The prefilled form is a worked example. Its base-unit inputs and expected outputs are shown below; use the reset button to restore it.
| Input | Example |
|---|---|
| Area | 100 |
| Target net water depth | 20 |
| System efficiency (separate losses) | 0.9 |
| Measured total flow | 10 |
Frequently asked questions
How should I choose the inputs?
Use measurements and local records for the stated period. All preset values are illustrative examples, not recommendations.
What does this result leave out?
Average flow does not guarantee uniform application. Catch-can measurements and cycle-and-soak may be needed to avoid runoff.

Garden irrigationCommon Irrigation Planning Mistakes
An area-based water volume is only the beginning. A working plan also needs outlet placement, operating pressure, flow, runtime and a watering window. Draw the route from source to each zone and note elevation changes. A calculator can produce a correct volume while the installation still fails to distribute it to the plants that require it.

Garden irrigationDrip Irrigation vs Sprinklers
Compare methods for the same planted area and required root-zone water. Drip can suit rows and individual plants; sprinklers can serve continuous areas where their distribution is appropriate. The comparison should include installation, filtration, pressure, maintenance and how planting changes over time. Do not select a method by quoting a universal savings percentage detached from the actual site.
