1. What is the Evaporation Formula?

The evaporation formula calculates the daily water loss from a surface due to evaporation. It's essential for water management in pools, reservoirs, agricultural applications, and environmental studies.

2. How Does the Calculator Work?

The calculator uses the evaporation formula:

Where:

• \( SA \) — Surface area (square feet)
• \( ER \) — Evaporation rate (inches per day)
• \( 7.48 \) — Conversion factor (gallons per cubic foot)
• \( 12 \) — Conversion factor (inches to feet)

Explanation: The formula converts the evaporation rate from inches per day to gallons per day by accounting for the surface area and unit conversions.

3. Importance of Evaporation Calculation

Details: Accurate evaporation calculation is crucial for water resource management, irrigation planning, pool maintenance, and environmental impact assessments.

4. Using the Calculator

Tips: Enter surface area in square feet and evaporation rate in inches per day. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect evaporation rate?
A: Temperature, humidity, wind speed, and atmospheric pressure significantly influence evaporation rates.

Q2: How can I measure evaporation rate?
A: Use evaporation pans, weather station data, or consult local meteorological records for accurate evaporation rates.

Q3: What are typical evaporation rates?
A: Rates vary by location and season, typically ranging from 0.1 to 0.5 inches per day in temperate climates.

Q4: Can this formula be used for any liquid?
A: The formula is specifically designed for water. Other liquids may have different densities and evaporation characteristics.

Q5: How accurate is this calculation?
A: Accuracy depends on the precision of your input values and how representative the evaporation rate is for your specific conditions.
