Is the flow rate for a public swimming pool measured in gallons per hour (GPH)?

The flow rate for a public swimming pool is typically measured in gallons per minute (GPM) rather than gallons per hour (GPH). This measurement reflects the rate at which water is circulated through the pool's filtration system, which is crucial for maintaining water quality and safety. Measuring flow in gallons per minute provides a more immediate and manageable understanding of water movement and is standard in the industry, allowing for timely adjustments to filtration and chemical treatments. Thus, the statement that flow rate for a public swimming pool is measured in gallons per hour is inaccurate.
