Irrigation Runtime
Convert a chosen water depth and emitter flow into runtime.
Your numbers
Required runtime
Assumes constant total emitter flow and the entered application efficiency. The water-depth target is chosen by you; crop needs, soil behavior and weather are not assessed.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use V = Ad/e and t = V/q. A is area in m², d is chosen water depth in mm, e is application efficiency as a fraction, and q is total emitter flow in L/min. V is litres and t is minutes.
Convert a chosen water depth and emitter flow into runtime.
Worked example
- Net area (m²)
- 20
- Chosen water depth (mm)
- 10
- Total emitter flow (L/min)
- 20
- Application efficiency (%)
- 80
- Required runtime
- 12.5 minutes
- Supply water volume
- 250 L
Scope and limitations
Assumes constant total emitter flow and the entered application efficiency. The water-depth target is chosen by you; crop needs, soil behavior and weather are not assessed.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
