A device, either physical or software-based, designed to compute the volumetric speed at which water circulates through a swimming pool’s filtration system. The calculation often considers pool volume, desired turnover rate (the time it takes to filter the entire pool volume once), and pipe dimensions. As an example, a user inputs the pool’s gallon capacity and the desired turnover rate in hours; the result will indicate the required gallons per minute (GPM) needed for the pump to achieve the stated filtration goal.
Accurate calculation is crucial for maintaining water quality and hygiene in swimming environments. Sufficient circulation and filtration prevent the buildup of contaminants, reduce chemical demand, and minimize the risk of algae growth. Historically, estimations were performed manually, leading to potential inaccuracies. The advent of these computational tools simplifies the process, ensuring more precise and efficient filtration system sizing and management.
