Aboveground Pool Sizes

Considering this, how many gallons is a round pool?

Length x width x depth x 7.5 = volume Length times width gives the surface area of the pool. Multiplying that by the depth gives the volume in cubic feet. Since there are 7.5 gallons in each cubic foot, multiply the cubic feet of the pool by 7.5 to arrive at the volume of the pool, expressed in gallons.

Secondly, how many gallons is a 12×30 pool? The colorful Intex Pool Set includes a 110-120V filter pump with a 530 gallon-per-hour flow rate and a water capacity at 90 percent of 1,718 gallons. An easy-to-understand setup and maintenance DVD is included with the Intex 12′ x 30′ Pool Set to help get you started.

Likewise, people ask, how many gallons is a 18×52 pool?

If you are lucky enough to have an Above Ground Pool, or some Inground Pools where the entire bottom is one Depth, it is very easy to figure out the Average Depth. It is just the Depth of the water.How Many Gallons Of Water Are In My Swimming Pool?

## Variable Depths With A Drop

If, instead of a gradual slope down to the deep end, your pool has a definitive drop between the shallow and deep ends, the average depth will be different, even if the shallow end and deep end are still, for example, 3 feet and 9 feet, respectively.

It may be easier, in this case, to treat the shallow and deep ends as separate pools. This will allow you to apply the volume of each section using the constant depth formula.

Once you have the volumes of both parts, simply add them together to determine the volume for the whole pool.

## Formulas Behind Pool Calculator

So you no longer need to worry “how many gallons is my pool?”, simply apply one of the formulas:

• Rectangular / square pool
• volume = length * width * / 2

The first two agents is, of course, the formula for the area of the rectangle.

• Oval / circle pool
• volume = * / 2

The first part of the equation comes from a standard area of an ellipsis formula: A = * a * b, where a, b are the distances between the center and the ellipse’s vertex, lying on the horizontal and vertical axes. In our case, we have the length and width values that are the doubled distances a and b, so in the final formula, we need to divide the surface area of an oval by 4.

You are wondering why we average the depths / 2? Have a look at the pictures:

• Here you have the standard rectangular pool. l stands for the length of the pool, w for width, d1 is depth on one end of the pool and d2 is the depth on the other end.
• Let’s take the right trapezoidal side of the pool. “Cut” the triangle, with one apex in the midpoint of the side, as in the picture.
• Flip and move it to the other side to form a rectangle. The edge of the new shape is the average of two sides, so
• / 2.

The area of such a rectangle is then length * / 2. Multiply it by the third dimension – the width – and you’ll get the final formula for rectangular pool volume:

• volume = length * width * / 2

## Variable Depth Pools: Square And Rectangular

Length x width x average depth x 7.5 = volume

Length times width gives the surface area of the pool. Multiplying that by the average depth gives the volume in cubic feet. Since there are 7.5 gallons in each cubic foot, multiply the cubic feet of the pool by 7.5 to arrive at the volume of the 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. Therefore, multiply the number of inches in your measurements by 0.0833 to get the appropriate percentage of one foot.

Example: 25 ft, 9 in. = 25 ft +

= 25 + 0.75

= 25.75 ft

If the shallow end is 3 feet and the deep end is 9 feet, and assuming the slope of the pool bottom is gradual and even, then the average depth is 6 feet.

Average depth = / 2

Average depth = / 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. Measure the length, width, and average depth of the shallow section, then take the same measurements for the deeper section. Calculate the volume of the shallow section and add that to the volume you calculate for the deeper section.

Length x width x average depth x 7.5 = volume

25.75 ft x 10 ft x 6 ft x 7.5 = 11,587.5 gallons

## How Does The Pool Volume Calculator Work The pool water calculator is a tool similar to the volume calculator it also uses also the formulas from the square footage calculator.

Finding the volume of a pool is a simple matter of getting the area of the surface of the pool and then multiplying that by the average depth.

• Start by entering the pool size .
• Then add its depth at the two endpoints.
• If there is both a shallow and a deep end, enter the shallow depth in the first field and the deepest point in the second. Otherwise, enter two identical values.
• If the depth of your pool changes drastically instead of gradually, you may want to consider dividing it in half, with a separate pool calculator measurement for each part .

You could go one step further and, knowing the density of water , work out how much the water in such a pool would weight.

Here is a great tool to calculate the volume or capacity of your pool. Important! Remember to measure from the depth of the water rather than the height of your wall.

More complicated pool shapes will require multiple calculations and adding them together. For more detailed information on the calculations, read more below the calculator. For additional help, contact a swimming pool professional.

Capacity calculations involve calculating surface area and volume of the pool or spa. This article describes in detail how to calculate the size and capacity of the pool you are planning. Calculating a pool’s area in square feet is the first step in determining information including pool gallons, maximum capacity of persons and other important information about your pool.

## How To Calculate Circular Pool Volume

You can calculate the volume of a circular swimming pool by multiplying 3.14 times the radius in feet times the radius in feet times the average depth in feet times 7.48. Thus, the formula is:

volume = r2× average depth × 7.48

The first part of this formula determines the area, and multiplying by the depth finds the volume. Multiplying by 7.48 finds the gallons of water per ft3 of water.

## How Many Gallons Of Water Does My Pool Hold

You can find out how many gallons your pool can hold using the pool volume calculator. First, you must know whether you plan to have an oval or a rectangular pool. Then you need to measure the dimensions of the pool. With all of this information, you can use the how many gallons is my pool calculator to find out the number of gallons you must purchase.

If your swimming pool doesnt have a varied depth instead, it has a fancy shape like a cylinder or a bow font, you may need to use a different calculator, one which provides options for various 3D shapes. Or if you plan to have a swimming pool with a custom or an odd shape, check with the manufacturer.

Its important for you to find out how many gallons you need to fill up your swimming pool so you can estimate how much it would cost you. When you know the number of gallons you need, then you can check the rates of the local water supply and perform the calculations. That way, youre ready with your budget when its time to have your swimming pool filled up.

## Pool With Variable Depth

How To Calculate The Number of Gallons In A Pool

For pools that have variable depth where you have to measure several times and add the volume of one shallow end to that of a deep end, measure the surface area of the shallow end multiply by the average depth of the same side, then multiply by 7.5 to get the volume of that side of the pool expressed in gallons.

Do the same on the deep end of the pool. Note that this process applies when a swimming pool has, say, two shallow ends from which you can find the average depth, and then a third, deep end.

## Pool Evaporation: How Much Water Do You Actually Lose

• |January 10, 2021

Evaporation is when liquid turns into a gas or vapor.

This process happens to almost any body of water under the right conditions, including swimming pools.

This means, as a pool owner, you lose a measurable amount of pool water every day through evaporation. Several thousands of gallons of water per year for an average residential pool, in fact.

Lets talk about why this happens, how to calculate the amount of water you lose through evaporation, and how to prevent it.

Quick answer: You can expect to lose between 2 mm to 2 inches of water in your pool per week due to evaporation, depending on the various factors well get into in this article.

## Irregularly Shaped Pool Volume

Not all pools are rectangular, square, or round. Some are oval, others are the classic kidney shape, and then some just wiggle all over the place, mimicking natural shorelines.

If you have an irregularly shaped pool, you can still calculate the volume. Youll just have to doyou guessed iteven more math!

The easiest way to calculate an oddly shaped pool is to imagine it broken down into two or more smaller, regularly shaped parts. Try to see smaller, individual squares, rectangles, or circles within the larger, irregular shape.

Once youve mapped them out, measure them, and then use the same formulae that apply to those regular shapes to calculate the volume in each smaller section. Then just add all the volume figures together, and youll have a pretty close approximation of the pools total volume.

Admittedly, this could also be known as the winging it procedure, and youre not going to get a completely accurate volume. If your pool is shaped like a fractal, your best bet is to have a professional take the measurements for you.

## Calculating The Volume Of Your Pool In Gallons

To calculate how many gallons of water your pool holds, you need to calculate its cubic volume.

To calculate the cubic volume, multiply the surface area of the swimming pool by the depth of the pool. It is therefore important to get the accurate, average depth of each side of the pool as shown previously, for best results.

There are 7.5 gallons in each cubic foot of water, so the product of the different dimensions will be multiplied by 7.5 to give the volume of water in gallons. Below is a simple breakdown of this formula for different pool types:

## How To Measure The Surface Area Of A Kidney

You already know by now that to get an accurate measurement of the surface area, it is ideal to measure severally the different bulges of the swimming pool.

• Find out which axis of the pool is the longest. Next, on an imaginary line, measure the length of that axis from one end to the other. You may want to measure again, just to be sure. Write down your findings.
• Check which bulge is wider, and measure the width with a ruler, writing your measurement down as A. Go to the smaller bulge of the pool and measure the width as well this time, writing down the measurement as B. In this case, it also helps to doublecheck to make sure you have the accurate figures.
• Calculate the surface area using the simple formula:
• 0.45 X X Length X Average depth X 7.5 = Volume of Kidney-shaped pool in gallons

A quick example: If a kidney-shaped pool is15 feet long, the wider bulge is 7 feet wide, the smaller one is 3 feet, andits average depth is 4.5 feet, the volume in gallons will be calculated asfollows:

0.45 X X 4.5 X 7.5 = 151.88 gallons.

All that being said, no matter the size or shape of your pool, there usually comes a time when the water becomes worn out and you have to drain it. Take advantage of our expert guide on How to Drain a Pool to do so in easy steps.
