Calculator Inputs and Outputs
Inputs
- Target water depth (in) — example: 0.75
- Sprinkler precipitation rate (in/hr) — example: 0.5
- Watering cycles — example: 2
Results
- Total sprinkler runtime (min)
- Runtime per cycle (min)
- Total runtime (hours)
Formula used
Runtime = target depth ÷ precipitation rate.
How to Use the Sprinkler Runtime Calculator
Enter the requested values, check the units and assumptions, then select Calculate Sprinkler Runtime. The built-in defaults provide a complete working example.
Formula
Runtime = target depth ÷ precipitation rate.
Understanding the Results
The primary answer appears first. Supporting outputs show related quantities, conversions, dates, costs, ratios, or intermediate values. Calculations keep additional precision before display rounding.
Accuracy Tips
- Use measured values and consistent units.
- Review assumptions, waste rates, fees, timing, and efficiency inputs.
- Recalculate after changing any project condition.
