1. What is Pool Flow Rate?

The pool flow rate is the rate at which water moves through the pool's filtration system, typically measured in gallons per minute (GPM). Proper flow rate is essential for maintaining water clarity and sanitation.

2. How Does the Calculator Work?

The calculator uses the flow rate formula:

Where:

• \( FR \) — Flow rate (gallons per minute)
• \( V \) — Pool volume (gallons)
• \( T \) — Turnover time (minutes)

Explanation: The formula calculates the required flow rate to completely turn over the pool's water volume in the specified time.

3. Importance of Proper Flow Rate

Details: Proper flow rate ensures effective filtration, chemical distribution, and water circulation. Most health codes require complete turnover every 6-8 hours (360-480 minutes).

4. Using the Calculator

Tips: Enter pool volume in gallons and desired turnover time in minutes (typically 360-480). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical turnover time for pools?
A: Residential pools typically aim for 6-8 hour turnover (360-480 minutes). Commercial pools often require faster turnover (30 min-4 hours).

Q2: How do I calculate my pool's volume?
A: For rectangular pools: Length × Width × Average Depth × 7.5. For circular pools: Radius² × 3.14 × Average Depth × 7.5.

Q3: What affects flow rate requirements?
A: Factors include bather load, presence of water features, pool shape, and local health codes.

Q4: How does flow rate relate to pump size?
A: Your pump should be sized to achieve the calculated flow rate while accounting for pipe size and system head loss.

Q5: What if my actual flow rate differs from calculation?
A: Check for clogged filters, improper pipe sizing, or pump issues. A professional may need to evaluate your system.
