Need a math wizard - how many gallons?

[Alan]

I'm looking at a fuel tank Sunday or Monday, I need help to figure out how many gallons it would hold. It's a round tank, the diameter is 47 inches and the length is 72 inches. Can anyone smarter than me tell me how many gallons it holds ..... or close to the amount of gallons?

Thanks,
Alan

This is as close as I could come

Closes I could come is aorund 70 gallons but that doesn;t seem right when I look at my tank that holds 135

I came up with just a squirt or two under 541 gallons if I converted the inches to feet correctly. Used http://www.dep.state.pa.us/dep/deputate/waterops/

I think that's were I had the problem converting cubic inches to cubic feet

1 cu ft is 12X12X12 or 144X12 or 1,728 cu in.

That is correct!

I bet you wont need a math wizard to calculate how much it will cost to fill it up. :shock: :nod:

Should be 540 gal. Check out this chart. :compute:

540 is right (A little over 540 can be held)

Here is your math:
Volume of Cylinder = Area of Base * Height = pi*r^2*h
=3.14* (47/12)^2 * (72/12)
=72.289 cubic feet

a cubit foot has 7.4805 gal so multiply that by 72.289 and you get a little over 540 gallons.

There you go..same answer three times. Oh by the way I figure about 540 gallons +/- a little depending on the ambient temperature.

=3.14* (47/12)^2 * (72/12)
=72.289 cubic feet

Cattlehand has the right number. He made me do the math just to make sure. It looks like he missed a number when he explained it. r= 47/2/12.

=3.14* (47/2/12)^2 * (72/12)
=72.289 cubic feet[/quote

Ya'll are hurting my brain.

At work I have the "convert" program that does it all for you. Metric to anything. Volumetrics etc. I am now seriously spoiled!

Since I am at home right now, I can't be much help to you Alan

good catch, yup I had typed it wrong :dunce: .

Any chance..... I mean, would you all mind double checking your work :lol2: Thanks for the help, sounds like 540 gallons + or -

Just remember...what it holds and what you put in are two different numbers...

I'll buy that! :clap: Remember you have to factor in the thickness of the tank. We are all calculating using outside dimensions. Capacity might be a tad shy of 540. :!:
