1. What is Pond Water Evaporation?

Pond water evaporation is the process where water changes from liquid to vapor and escapes from the pond surface. It's influenced by temperature, humidity, wind speed, and surface area.

2. How Does the Calculator Work?

The calculator uses the evaporation formula:

Where:

• \( SA \) — Surface area of the pond (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 calculates daily water loss by converting surface area and evaporation rate into gallons per day.

3. Importance of Evaporation Calculation

Details: Calculating evaporation helps pond owners manage water levels, plan for refilling, understand water loss patterns, and maintain healthy aquatic ecosystems.

4. Using the Calculator

Tips: Enter surface area in square feet and evaporation rate in inches per day. Typical evaporation rates range from 0.1 to 0.5 inches per day depending on climate conditions.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect evaporation rate?
A: Temperature, humidity, wind speed, sunlight exposure, and water temperature all influence evaporation rates.

Q2: How can I reduce evaporation from my pond?
A: Use pond covers, plant shade trees around the pond, reduce surface agitation, and maintain proper water depth.

Q3: What is a typical evaporation rate?
A: In moderate climates, 0.1-0.3 inches per day; in hot, dry climates, 0.3-0.5 inches per day or more.

Q4: When is evaporation highest?
A: During summer months, hot windy days, and periods of low humidity.

Q5: How accurate is this calculation?
A: It provides a good estimate but actual evaporation may vary based on local microclimate conditions and pond characteristics.
