Irrigation run time
Convert a chosen water depth and measured application rate into time.
How this works
Minutes = requested depth / measured application rate × 60.
Example
Using the example inputs, run time is 40 minutes.
- Desired application depth
- 10 mm
- Measured application rate
- 15 mm/hour
- Watered area
- 100 m²
- Run time
- 40 minutes
Scope and assumptions
Does not recommend plant watering amounts; account for runoff, restrictions, and local conditions.
