# Thread: Varying info on how much H20 27'x52" holds.

All pool equipment is based on pool size and amount of water. Can anyone tell me the correct answer for 27' round w 52" walls?

I have a 17' x 54" and the manual says 17,000 gals.

Volume is going to be based on water height, so you want to use the planned depth of the water, not the height of the walls, if you're plugging into an online calculator.

If you have 4 feet of water in the pool I get 17130 gallons:

radius of pool is diameter/2 or 13.5 feet, pi * radius ^^2 * 4 feet deep = 2290 cubic feet, 2290 x 7.48 (# US gallons per cubic foot) = 17130

Measure the actual water depth in inches and adjust accordingly, eg if 50 inches deep then volume is 17130 * 50 / 48.

This assumes the inside of the pool is exactly 27 feet... these days companies seem to claim whatever they can get away with so it's probably 25-1/4 feet or something
