1. What is the Concrete Pond Evaporation Rate?

The evaporation rate for concrete ponds is typically estimated at 5 mm per day. This calculator helps determine the daily water loss in cubic meters based on your pond's surface area.

2. How Does the Calculator Work?

The calculator uses the evaporation rate equation:

Where:

• \( Rate \) — Daily water loss (m³/day)
• \( Area \) — Pond surface area (m²)
• 5 mm/day — Standard evaporation rate for concrete ponds
• 1000 — Conversion factor from mm to meters

Explanation: The equation converts the standard 5 mm/day evaporation rate to cubic meters based on your pond's surface area.

3. Importance of Evaporation Calculation

Details: Knowing your pond's evaporation rate helps in water management, planning water replenishment, and understanding seasonal water loss patterns.

4. Using the Calculator

Tips: Enter your pond's surface area in square meters. The value must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Is 5 mm/day accurate for all concrete ponds?
A: This is an average value. Actual rates may vary based on climate, wind exposure, and water temperature.

Q2: How does this compare to other pond materials?
A: Concrete ponds typically have slightly higher evaporation rates than lined or earthen ponds due to heat absorption.

Q3: Should I adjust for seasonal variations?
A: Yes, evaporation rates can be 2-3 times higher in summer than in winter months.

Q4: How can I reduce evaporation?
A: Using shade structures, floating covers, or reducing surface agitation can help minimize evaporation.

Q5: Does water depth affect evaporation rate?
A: No, evaporation is primarily a surface phenomenon and not significantly affected by water depth.
