How to Use This Calculator

Enter Area to suppress (yd²), Wind speed (mph), and Temperature (°F).
Set Relative humidity (%).
Review the Daily water needed (gal) result.
Use Water per application (gal) and Applications per day to inform your decision.

How the result changes with Wind speed (mph)

Area to suppress (yd²): Total unpaved area requiring dust control in square yards.
Wind speed (mph): Average sustained wind speed. Dust emissions scale with wind^1.3.
Temperature (°F): Ambient temperature. Higher temps increase evaporation rate.
Relative humidity (%): Ambient relative humidity. Lower humidity means faster drying.

Daily water needed (gal): Total gallons of water required per day for dust suppression.
Water per application (gal): Gallons of water per single application pass.
Applications per day: Recommended number of water applications per day.
Wind adjustment factor: Multiplier based on wind speed relative to 10 mph baseline.
Target soil moisture (%): Recommended surface moisture content for effective suppression.
Water truck loads/day: Number of 4,000-gallon water truck loads needed daily.
Monthly water cost ($): Estimated monthly water cost at $0.005/gallon bulk rate.

Identify Input Parameters
4 parameters
Area to suppress (yd²) = 5000, Wind speed (mph) = 15, Temperature (°F) = 85, Relative humidity (%) = 30 = 4 input(s) provided
Calculate Daily water needed
Daily water needed = waterPerApp * appsPerDay
16940 = 16940
Calculate Water per application
Water per application = areaSqYd * baseRate * windFactor
4235 = 4235
Calculate Applications per day
Applications per day = max(1, min(8, round(2 * evapFactor)))
4 = 4
