ClarityHow to use this tool
- Enter area to cover, water depth, total flow rate.
- Select Calculate to view the result.
- Check the method and assumptions below before using the result.
Input reference and sample values
Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.
| Input | Format and units | Sample |
|---|---|---|
| Area to cover | Numeric value. Unit: m². Must be greater than zero. | 20 |
| Water depth | Numeric value. Unit: mm. Must be greater than zero. | 10 |
| Total flow rate | Numeric value. Unit: L/min. Must be greater than zero. | 20 |
Result for these sample inputs
10 minutes
Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Minutes = area × depth(mm)/flow(L/min), because 1 mm over 1 m² is 1 liter.
Using area to cover = 20 m², water depth = 10 mm, total flow rate = 20 L/min, the result is 10 minutes. Change these example inputs to match your task; use the method above to check each step.
What to keep in mind
Assumes uniform application and no runoff or evaporation. A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.
