1. What is the Swimming Pool Evaporation Rate Calculator?

The Swimming Pool Evaporation Rate Calculator estimates the daily water loss from a swimming pool due to evaporation. This is particularly important for UK pool owners to manage water consumption and maintenance schedules effectively.

2. How Does the Calculator Work?

The calculator uses the evaporation rate formula:

Where:

• \( SA \) — Surface area of the pool (square meters)
• \( ER \) — Evaporation rate (millimeters per day)
• 1000 — Conversion factor from cubic meters to litres
• 25.4 — Conversion factor from millimeters to inches

Explanation: The formula calculates the volume of water lost through evaporation by multiplying the surface area by the evaporation depth and converting to litres per day.

3. Importance of Evaporation Rate Calculation

Details: Understanding evaporation rates helps pool owners plan water replenishment, reduce water waste, and maintain proper chemical balance. In the UK climate, evaporation can significantly impact pool maintenance costs.

4. Using the Calculator

Tips: Enter the pool surface area in square meters and the daily evaporation rate in millimeters. Typical UK evaporation rates range from 2-6 mm per day depending on weather conditions.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical evaporation rate for UK swimming pools?
A: In the UK, typical evaporation rates range from 2-6 mm per day, with higher rates during warm, dry, windy conditions and lower rates during cool, humid weather.

Q2: How can I reduce pool evaporation?
A: Using pool covers when not in use, reducing water temperature, and installing windbreaks can significantly reduce evaporation rates.

Q3: Does evaporation affect pool chemistry?
A: Yes, evaporation concentrates chemicals and minerals in the pool water, requiring regular testing and adjustment of chemical levels.

Q4: How accurate is this calculation?
A: The calculation provides a good estimate, but actual evaporation can vary based on temperature, humidity, wind speed, and pool usage.

Q5: Should I be concerned about evaporation in winter?
A: Evaporation still occurs in winter, though at lower rates. Proper winterization and covering are essential to minimize water loss and protect the pool.
