What is the minimum required circulation through the filtration system for a 16' X 30' pool with an average depth of 5'-6"?

To determine the minimum required circulation through the filtration system for a pool, it's essential to first calculate the volume of the pool. For a pool that measures 16 feet by 30 feet with an average depth of 5.5 feet (5 feet 6 inches), the volume can be calculated using the formula for the volume of a rectangular pool:

Volume = length × width × average depth

Converting the dimensions into consistent units (inches to feet), the volume becomes:

Volume = 16 ft × 30 ft × 5.5 ft = 880 cubic feet.

Next, we need to convert that volume into gallons since pool circulation rates are usually expressed in gallons. There are 7.48 gallons in a cubic foot, so:

880 cubic feet × 7.48 gallons/cubic foot = approximately 6584 gallons.

The general rule of thumb for pool circulation is that the water in the pool should be cycled through the filtration system at least once every 8 hours. The minimum rate of circulation is typically set as a percentage of the total pool volume, which is generally 1/8 of the total volume over an 8-hour period.

To find the minimum required circulation per hour, divide the total
