How big does a cylinder tank have to be in order to hold 100 gallons of water?

Answer 1

The tanks capacity should be: 100 x 4.5461 litres =454.61 litres or 454.61/1000 x1.3080 x 27 =16.055 cft.

1 ***=1.3080 cu yd=1.3080 x 27=35.316 cft
1gallon=4.5461 litres.
Capacity of tank=454.61 lit or 35.316 cft.

Answer 2

You need to convert this to cubic inches. There's many conversion charts available, such as: http://www.allmeasures.com/.

In this case, 1 gallon equals 231 cubic inches. Since you have 100 gallons, you have 23,100 cubic inches.

The volume of a cylinder is pi*r^2*h where r is the radius and h is the height. That gives you quite a few choices for the dimensions of your cylinder. Letting the radius equal the height makes for a nicely shaped cylinder and makes your calculation a one-step process: r equals the cube root of 23100/pi, or about 19.5 inches.

That's only one example. The key is to pick two numbers where r^2 * h = 23100/pi.

Answer 3

100 gallons is 13 cubic feet, so if the base is 2 feet in diameter, it would need to be about 4 feet tall (3.14x1x4). But that's round numbers. I added a link to show you a place you can get a neat little dimension converter (convert.exe) to help with this.

You could also search online at hardware stores to see different shapes.

Answer 4

one square foot of water = 7.5 gallons
so
100 / 7.5 = 13.333 sq. ft.
volume of a cylinder = pi x (r x r) x h where r = radius, h = height
so
13.333 = 3.14159 x (r x r) x h
13.333 / 3.14159 = 4.244 =(r x r) x h
if r =1, then h = 4.244
so
your cylinder is 2 feet across and 4 1/4 feet tall

Answer 5

Big as in tall, or big as in wide or big as in volume? If the tank is one inch wide then it will need to be really tall. If the tank is one inch tall then it will need to be fairly wide. Be more specific with your question.

Answer 6

I'm no mathmatician, but i'd say twice the size of a 50 gal drum.

Answer 7

Omg people know the answer to this question? Wow I am impressed!

Answer 8

pi*r^2*h=volume=100gallons
