Since there are 7. Multiplying that by the average depth gives the volume in cubic feet. 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. Therefore, multiply the number of inches in your measurements by 0. 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. 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. Make sure to use the actual water depth in your calculations, not the depth of the container. For example, the hot tub depicted in Figure 2 is 4 feet deep, but the water is only filled to about 3 feet. Using 4 feet in this calculation will result in a volume 33 percent greater than the actual amount of water.
This could mean serious errors when adding chemicals for example, which are administered based on the volume of water in question. There might be a time when you want to know the potential volume, if filled to the brim. Then, of course, you would use the actual depth or average depth measurement. In the example, that was 4 feet. The number 3.
The radius is one-half the diameter, so measure the distance across the broadest part of the circle and divide it in half to arrive at the radius.
Squared means multiplied by itself, so multiply the radius by itself. For example, if you measure the radius as 5 feet, multiply 5 feet by 5 feet to arrive at 25 feet. Use the hot tub to calculate the volume of a round container. Let's do the tricky part first. The diameter of the tub is 10 feet.
Half of that is 5 feet. Squared multiplied by itself means 5 feet times 5 feet equals 25 square feet. Knowing this, you can return to the formula:. In measuring the capacity of a circular spa , you might need to calculate two or three areas within the hot tub and add them together to arrive at a total volume.
An empty circular hot tub looks like an upside-down wedding cake, because of the seats. Therefore, you might want to treat it as two separate volumes-the volume above the seat line and the volume below. In the wooden hot tub, where there is actually water above and below the seats, the tub can be measured as if there are no seats because this difference is negligible.
There are two methods used to calculate the capacity of irregular shapes. First, you can imagine the pool or hot tub as a combination of smaller, regular shapes.
Measure these various areas and use the calculations described previously for each square or rectangular area and for each circular area. Rectangle shaped pools look best for this size. Lap pools are long, narrow, and typically rectangular pools. Most rectangular pools are about twice as long on one side as they are on the other, with an average depth of around 5.
Typical swimming pool dimensions are 10 x 20, 15 x 30, and 20 x It turns out that Olympic swimming pools have some pretty specific dimensions.
They are 50 meters long, 25 meters wide, and 2 meters deep. In terms of volume, when full, these pools hold 2. Begin typing your search term above and press enter to search. Press ESC to cancel.
