# How do I calculate the volume of water in my pool?

## How do I calculate the volume of water in my pool?

Length x width x average depth x 7.5 = volume (in gallons) Length times width gives the surface area of the pool. Multiplying that by the average depth gives the volume in cubic meters. If you’d like to find the pool volume in gallons, multiply your results by 7.5, as there are 7.5 gallons for each cubic foot.

## How do I calculate the surface area of my pool?

1. FORMULAS. Surface Area (Circle): Radius x Radius x 3.14 (Radius = Diameter / 2) Surface Area (Rectangle/Square): Length x Width.
2. EXAMPLE. A rectangular pool is 50 feet long by 20 feet wide. The shallow end is 3 feet deep and the deep end is 7 feet deep.
3. ANSWERS. Surface Area = 1,800 square feet Volume = 81,000 Gallons.

How do I calculate how much paint I need for my pool?

Next, to determine the number of 1 gallon kits needed to paint the Total Area, divide by 300 (the average coverage rate of our paint) and multiply by 2 (because you will need two coats). TA/300 x 2 = number of gallon kits needed (round up). Total Area = 810 sq. ft.

How do you find volume with surface area and depth?

Effectively, for cylinders and prisms, the volume is the area of one side multiplied by the depth or height of the shape. The basic formula for volume of prisms and cylinders is therefore: Area of the end shape × the height/depth of the prism/cylinder.

### How do I measure the size of my pool?

Measure the Pool Measure the size of your pool in feet. Use a measuring tape and lay it down one side of the pool and measure the length, ensuring that it is parallel to the edge of the pool. To measure width, begin at a corner of the pool and measure from that corner to the closest corner.

### How many gallons is a 12×12 pool?

Above Ground Pools with a Depth of 48″ (4′)

SIZE GALLONS OF WATER
12′ Round 3,398
15′ Round 5,310
18′ Round 7,646
21′ Round 10,407

What is the formula for a surface area?

Variables:

Surface Area Formula Surface Area Meaning
SA=2B+Ph Find the area of each face. Add up all areas.
SA=B+12sP Find the area of each face. Add up all areas.
SA=2B+2πrh Find the area of the base, times 2, then add the areas to the areas of the rectangle, which is the circumference times the height.

How do you figure surface area?

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

#### How do you calculate maximum pool capacity?

If the maximum depth of the pool is 5 feet, it can accommodate: 1,300 ÷ 20 = 65 people. If the entire pool is more than 5 feet deep, the capacity increases to: 1,300 ÷ 15 = 86 people. If only half of the pool is more than 5 feet deep, the capacity is: (650 ÷ 20) + (650 ÷ 15) = 76 people.

#### How much paint in square meters do you need to paint the pool?

40 – 50 sq metres per 5.0 Litres per coat @ 25 microns dry film thickness. 30 – 40 sq metres per 5.0 Litres @ 25 microns dry film thickness.

How do you find the width of a volume?

V=l×h×w , where V= Volume, l= length, h= height, and w= width.

What is area formula?

The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

## How to calculate the cubic volume of a pool?

The cubic volume can be calculated by including the depth of the pool with the surface area. For accurate calculations, the pool should be divided into various areas according to the depth. Constant Depth Pools: Square or Rectangular Length x width x depth x 7.5 = volume (in gallons)

## How to calculate the average depth of a swimming pool?

Average depth = (Depth at the shallow end + Depth at the deep end) / 2 Average depth = (3 + 9) / 2 = 6 feet. If most of the pool is only 3 or 4 feet and then a small area drops off suddenly to 10 feet, you will have a different average depth. In such a case, you might want to treat the pool as two parts.

How tall is an inch in a pool?

Measure the length, width, and average depth of the pool, rounding each measurement off to the nearest foot or percentage of one foot. One inch equals 0.0833 feet.

Which is heavier a gallon of water or chlorine?

This becomes obvious since a gallon of water weighs 8.3 pounds but a gallon of chlorine weighs 10 pounds (in a 15 percent solution). The chlorine is a denser liquid; there’s more of it than an equal volume of water.
