2/1/12th GALLON
How many gallons will fit into a 24 foot diameter x 4 foot high round swimming pool
A round pool with a 10-foot diameter and a 3-foot depth can hold up to 1,762 gallons of water.
A three-inch diameter pipe one foot long holds 0.367 gallon.
33Volume of cylinder = 56.5488 cubic feet.US gallon = 0.1337 cubic feetImperial gallon = 0.1605 cubic feetCylinder capacity = 422.95 US gallons or 352.33 Imperial gallons.
21 foot what? Radius, diameter or circimference? Presumably 4 feet deep?
Cannot be answered with only these measurements. You need to specify what shape the pool is. Also, for a rectangular pool, the length, width and depth are needed. For a round pool, the diameter and depth are needed.
A 12 inch diameter round pipe will hold 4.89 UK gallons or 5.88 US gallons per foot.
If that is 4 feet tall and 18 inches in diameter, it would be 16.83 gallons.
1,000,000 US gallons is about 134,000 cubic feet. A round tank of 56 feet diameter by 56 feet high will hold 1 million US gallons. Also a round pond of about 413 feet diameter by 1 foot deep.
To calculate the volume in gallons of a round pool, do the following calculation: diameter x diameter x depth x 5.9 Example: 28ft x 28ft x 4ft x 5.9 = 18,502.4 gallons
It is 7.83 gallons per inch. .785x4x4x1=12.56 cubic feet. 12.56 cubic feet x 7.48 gallons per cubic foot=93.9 gallons per foot 93.9 gallons per foot / 12 inches per foot =7.83 gallons per inch.
A 4-inch diameter cylinder holds 0.7 gallons per foot of depth.
