Length times width gives the surface area of the pool. Multiplying that by the average depth gives the volume in cubic feet. Since there are 7.5 gallons in each cubic foot, multiply the cubic feet of the pool by 7.5 to arrive at the volume of the pool (expressed in gallons).
Grab a Calculator and Letâs Figure This Out. Now that you know the gallons per minute and the amount of gallons in your pool you can find your run time. The math is simple. For the example, lets just say you have a 20,000 gallon pool with a GPM (gallons per minute) of 40. Grab that calculator and just âsub inâ your measurements for mine.
