You didn't provide enough information to fully answer this question. Volume requires 3 dimensions, and you provided 2 (or didn't fully explain the 3rd). To determine volume, you need length, width and height LxWxH=Volume. I'll explain how to solve this math problem the best way I can. 1 gallon = 231 cubic inches http://www.onlineconversion.com/volume.htm Now that you know there are 231 cubic inches per gallon, determine the volume of water you need in inches. I'm going to guess you were meaning the tube is 12 inches long and either a 4 inch diameter. Volume of a cylinder can be acheived by multipling the area of the base times height. Assuming your cylinder is a perfect circle with an inside diameter of 4 inches, the base would be PI * r2 or 3.141592 * (2*2) or 12.535668 inches square. Multiply this times the height (12), and you'll get the cubic inches required to fill the cylinder...or 150.796416 cubic inches. Divide by 231 (cubic inches per gallon) equalling .6528 US gallons required to fill the tube.
615,142 gallons of water are needed to fill this cylinder.
16 and 7/8
2,005 gallons of water are needed.
10 gallons of water are needed.
Round Pool: Depth x Diameter-squared x 5.9 = Volume in Gallons
It would require 2,937.6 US gallons of water to fill the pipe.
It requires 73 gallons of water to fill a 6 inch x 50 foot hose
You will need a maximum of 11,230 gallons of water.
Exactly 5264.1669 gallons
Approximately 26,802,130 US gallons.
4178 US gallons, approx.
The standard is four one-inch tablets per 10,000 gallons of water, so 3,800 gallons would be one and a half one-inch chlorinating tablets.
It would take 82.2857 gallons of water to fill a 2 inch pipe 504 feet long. The volume of the pipe is 19,008 cubic inches and there are 231 cubic inches of water in a gallon.
About 5869.24 gallons
4.578 gallons for every inch the water is deep.
A standard fire hose is 50 feet long. A hose this length with a 2-inch radius grants about 4.36 cubic feet. This volume holds 32 gallons of water.
It holds 4.987 gallons for every inch the water is deep.
1 cubic inch of water is 0.004329 US gallons.
that is about 105 cubic feet, and if you fill with water,which has 7.48 gallons per cu ft, that is 7.48 x 105 = 782 gallons
94 gallons of water.
