PUTTING IT INTO PRACTICE
Drip Water Per Plant: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Emitter flow (L/hour) | 2 |
| Emitters per plant (integer) | 2 |
| Runtime (minutes) | 30 |
| Result | 2 L/plant |
- Check the input labels and enter the example values above.
- Apply the relationship: Per-plant volume = flow × emitters × minutes/60.
- The result is 2 L/plant, rounded for display.
How to interpret your result
Uses equal functioning emitters and constant flow.
A water-budget conversion does not establish the crop’s requirement. Use measured flow and effective rainfall where possible. Distribution losses and runoff can make gross application differ from water retained in the root zone.
Frequently asked questions
Does one millimetre of rain equal one litre?
It equals one litre over each square metre of collection area. Total volume therefore depends on both depth and area.
When is the drip water per plant calculator useful?
Find water delivered per plant during a drip-irrigation interval. Uses equal functioning emitters and constant flow.
How do I use the drip water per plant calculator?
Enter emitter flow (l/hour), emitters per plant (integer), runtime (minutes). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Per-plant volume = flow × emitters × minutes/60.
What should I check before using the result?
Uses equal functioning emitters and constant flow.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
