The term refers to a tool or process used to determine the appropriate capacity of a water circulation device for a swimming pool. This typically involves assessing factors such as pool volume, filtration needs, and desired turnover rate. For example, a larger volume pool requires a device with a higher flow rate to ensure adequate water circulation and sanitation.
Determining the correct capacity is critical for energy efficiency, effective water treatment, and equipment longevity. An undersized device will struggle to adequately circulate and filter the water, leading to poor water quality and potential equipment strain. Conversely, an oversized device can consume excessive energy and may not be optimal for filter performance. Historically, approximations were used, but modern tools allow for more precise calculations based on individual pool characteristics.
