I need the formula for finding the volume of water in a round swimming pool?

Question

How many gallons of water

Answer 1

Round pool will be semi cylinder and the formula will be ½*pi*r^2*h where r will be the radius of curvature and h thelength of the pool
However if it is a closed round pool it will be pi*r^2*h
If the dimensions are in feet you will get the answer in cft and the conversion factor for converting cft into gallons will be 7.481

Answer 2

To do that, you need to know four different numbers: the length, width, average depth, and a multiplier that determines gallons. Here is the formula:

Length * Width * Average Depth * Multiplier = Gallons

Determine the Multiplier:

Rectangle, square, or free-form pool:multiplier = 7.5.

Round or Oval pool: multiplier = 5.9

Determine the Average Depth:

To determine the average depth in a pool where the bottom slopes, measure the shallow end, the the deep end depth. Add them together and divide by two (2).

Example: Shallow End = 2'. Deep End = 10'

2' + 10' = 12'; 12'/2 = 6' Average Depth

Answer 3

The volume of water in any shape first requires you to find the area of that shape.

For a circle that would mean using the formula pi x r x r = A

Next is finding out the depth of the pool and multiplying it with the area, A.
A x depth = Volume

This is of course assuming that the shape of the pool in constant with depth.


The same with a triangular pool.

First find the area = 0.5 x base x height = A
Then find the depth and multiply it with the area: A x depth = Volume.

So you see, each of the examples follw the same method and steps. Just remember the steps and you cant go wrong.

Answer 4

That's simple. Get one gallon of milk, empty the bottle. Fill the bottle with water, then add formula, pour into the swimming pool until the swimming pool is full, then you will know how many gallons.

Sorry I had too, Hahahaha !!

Answer 5

Assuming a circular backyard pool with constant depth, the volume of the pool in cubic feet would be 3.14 x depth x r^2 (radius squared).

There are 7.481 gallons in a cubic foot so the number of gallons would be 7.481 x 3.14 x depth x r^2

Answer 6

Volume = Length x width x height

Answer 7

My answer is the same but not really...
You must get the formula of a sphere then get the dimensions of the water (volume etc.) then use those and relate it to the vol. of sphere form.

Answer 8

1. measure the distance across the pool, from side to side. (diameter)
2. divide that in half to get the radius.
3. find the height of the pool
4. now is where the math comes in....
5. 3.14 x radius x radius x height
6. hopefully this helped!

Answer 9

(pie)*r^2*h
it's the same as that of the cylinder... where h is the height of the water in the pool... and (pie)*r^2 the base area
hope this helps =)

Answer 10

campare the volume with standard tanks---overhead tanks used in houses
