# Thread: Calculating my pool volume - or - Geometry is fun!

1. ## Calculating my pool volume - or - Geometry is fun!

For years I have wanted to do a precise calculation of the gallon size of my pool. I've used many online calculators and have gotten about as many different estimates as there are calculators out there. The answer doesn't matter that much, I just really wanted to figure it out, do the math, and let that section of my brain get a little excersize.

I found an old schematic of my pool with dimensions, which makes it pretty easy. Yes, the pool is not going to match the schematic exactly, and none of the sides are perfectly straight, and none of the corners are truly square.

The following calculations assume 36" of water fill in the shallow end.

Whew. Roughly 29,000 gallons.

You could also try chemical methods of determining volume such as:

That's pretty cool! Thanks for posting.

Do you have the "Simplified Formula Numbers" chart as well? You can't do the calculations without it.

I think I'll find a pretty darn good estimate when I get the water bill for my complete fill-up 6 weeks ago!!! ugh....

5. ## Re: Calculating my pool volume - or - Geometry is fun!

if you want to have some real fun, use calculus!!

Forgot that part...

This one is on that site too, but not sure if needed.

Mmmmmm, integrating over the pool volume. That would require a triple integral!!!! YUM!!

Integral or differential? I think I may have used calculus one time in real life. I don't remember what I used it for, but I was so happy to finally use something from those 3 semesters.

You hope. Same feeling I get when they deliver heating oil.

Only 3 semesters? You missed out on Diff-Eq (Differential Equations)!!! LOL

Heating oil...I've heard of that stuff....

I had Diff-Eq. Another waste of time in my young life. Thanks for reminding me. Most of grad school memory cells have been repurposed, or killed off by alcohol because they were weak and deserved to die.

I WAS eating popcorn!! Now I'm picking it off my computer screen and the folks here at work are looking at me that way, again.

Do you mean try chemical methods to check if the chemical method is accurate?
