Available Water Flow Test Calculator
Measure bucket or meter flow and record dynamic pressure.

Irrigation & Sprinkler Systems
Move from measured supply to feasible zones, application rate, runtime and fault finding without confusing flow, dynamic pressure and water depth.
Flow is quantity per time. Dynamic pressure is energy while water is moving. Precipitation rate is depth per time. Runtime supplies a chosen depth.

The irrigation workflow
SourceStoragePumpingIrrigationZonesUse
First measure flow and dynamic pressure. Then create zones that pass both flow and pressure checks, calculate application rate, schedule water and investigate weak coverage with evidence.

Sprinkler Precipitation Rate Calculator
For sprays and rotors: use actual nozzle flow and layout.
Use tool →Drip Irrigation Flow & Zone Calculator
For drip: total direct emitters or row geometry, never both.
Use tool →Sprinkler Low-Pressure Troubleshooter
For weak coverage: isolate scope, demand, restriction, leak and source evidence.
