In stimulate to number out the suitable doses of chemicals for her pool, you require to recognize how plenty of gallons of water the holds. To do that, you have to use a ruler to measure up your pool to uncover out this four various numbers; Length, Width, typical depth and a multiplier the determines gallons.
You are watching: How many gallons in a 15x30 pool
So right here are the formulas to number out exactly how much water is in your swimming pool:These formulas organize true because that both Inground pools too as over ground pools.
Rectangular, Square or Free kind Pools:
Length x width x typical Depth x 7.5 = complete gallons
For example: 16′ x 32′ x 4.5′ x 7.5 = 17,280 Gallons
Circular Pools:
Diameter x Diameter x median Depth x 5.9 = full gallons
For example: 18′ x 18′ x 4′ x 5.9 = 7,646 Gallons
Oval Pools:
Length x width x median Depth x 5.9 = full gallons
For example: 15′ x 30′ x 4′ x 5.9 = 10,620 Gallons
How to identify the median Depth that a swim Pool where the bottom slopes:
Below is a side-shot of the “typical” inground pool that has actually a shallow finish (see “D”), then a slope the leads into the deep finish (see “C”).
First measure the depth that “D”, the shallow finish (usually anywhere from 3′ come 5′), and also then measure the depth of “C”, the deep finish (usually anywhere between 6′ and also 12′) . Then, add them together and divide through 2. This is the typical depth of her pool.
For example, if your shallow end “D” is 3′, and your deep finish “C” is 8′, this would be her formula for the average Depth:
3′ + 8′ = 11′
11′ separated by 2 = 5.5.
Therefore, in this example, your mean depth would be 5 1/2 feet.
