Example Data Table
| Scenario | Area | Base rate | Apps/day | Days | Loss | Eff. | Safety | Total with safety |
|---|---|---|---|---|---|---|---|---|
| Haul road section | 3,000 m² | 0.9 L/m²/app | 4 | 10 | 12% | 85% | 10% | ~ 1,436 m³ |
| Open yard | 1,200 m² | 0.6 L/m²/app | 3 | 7 | 8% | 90% | 10% | ~ 169 m³ |
| Stockpile perimeter spray | 450 m² | 1.1 L/m²/app | 5 | 14 | 15% | 80% | 15% | ~ 519 m³ |
Examples are illustrative. Adjust rate and losses for material type, traffic, and climate.
Formula Used
1) Area
If area is not entered: Area = Length × Width
2) Adjusted application rate
AdjustedRate = BaseRate × (1 + Loss%) ÷ Effectiveness%
This increases demand for overspray, evaporation, wind drift, and poor coverage.
3) Daily and total water
Daily = Area × AdjustedRate × ApplicationsPerDay
Total = Daily × ProjectDays
4) Safety factor and truck loads
TotalWithSafety = Total × (1 + Safety%)
TruckLoads = TotalWithSafety ÷ TruckCapacity
