Ahead of discussing how to calculate gallons in a pool, let us understand what it is. To calculate gallons in a pool is the same as calculating the volume of a pool in gallons.
This concept is essential for example, when you are putting chlorine in a pool it is important to know the volume of a pool so that you can make accurate chemistry adjustments.
Formula to calculate gal in a pool.
These calculations mostly depends on the shape of the pool. For regular shapes, we use the formula to calculate the volume. For instance if the pool’s cross-section is circular, we use the formula to calculate the volume of a cylinder.
For the irregular shaped pools, you can imagine the pool 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
Example 1:
Suppose you have a pool with a rectangular cross-section and it has a length of 8 meters and a width of 5 meters, if its depth is 7 meters, calculate the gallons in the pool.
We begin by finding the of the rectangular pool in meters.
Thus, the volume of the pool is 280 m³.
Since we know that to convert cubic meters (m) into gallons, you multiply the cubic meters by 264.172. Therefore;
Hence, the U.S. gallons in that pool are 73.968.16
Example 2:
Suppose you have a circular pool. If you measured its radius and found it to be 700 cm and its height is 154 cm. Calculate the amount of water in the pool in gallons.
Volume of a Cylinder = π x radius2 x height
= 22/7 x 700 x 700 x 154
Therefore, the volume of the pool is 237,160,000 cm3
To convert cm3 to gallons, we divide the cubic centimeters by 3,785.41.
= 237,160,000 ÷ 3,785.41.
Thus, the capacity of the pool is 62,651 gallons.
