∙ 14y agoYou need to figure the volume of the pool: width x length x height in feet, then multiply by 7.5 to get gallons. Assuming your ends are round, yours would be something like 15 x 27 (for the middle) plus 7.5^2 x pi for the circular ends, all times 4 feet for the depth, or a total of 2327 cubic feet. Multiply by 7.5 to get 17451 gallons.
Now, if you want an 8 hour turnover (recommended) then you'd want 2181 gal/hour, or 36 gpm. Add in a safety factor (partially clogged filter, etc.) and somewhere around 50 gpm should be fine. Don't overdo it, though, too much volume is not good either.
A: More simply put would be more like 12 t 18 hrs depending upon use or bather load - - how many people, dogs etc in pool for what length of time - 8 hrs would be the minimum if the pool were not used.

∙ 13y agoWhen filled to 80% water capacity, as recommended, the pool holds approximately:
10'x30" = 915 gal
12'x30" = 1,353 gal
12'x36" = 1,722 gal
15'x36" = 2,561 gal
15'x42" = 3,110 gal
16'x42" = 3,896 gal
18'x36" = 3,735 gal
18'x42" = 4,814 gal
18'x48" = 5,593 gal
24'x48" = 10,103 gal

If you fill it with 4 feet of water (48 inches), the pool will contain about 5,310 gallons of water.
367.2 (rounded)
6 inches = 1/2 foot(40-ft x 20-ft x 0.5-ft) x (12 inches per foot)3 / (231 cubic inches per gallon) = 2,992.2 gallons (rounded)
The pool holds 7,600 gallons of water
This 8-foot round pool, when filled with 27 inches of water, is holding about 850 gallons of water.
(3.5 feet) * PI * ((9 feet)^2) = 6 662.46122 US gallons
598 Imperial gallons, approx.
192 inches (16 feet) of water in a 27-foot round pool is about 68,820 gallons.
