The volume of a cylinder is given as V = pi * r^2 * h. In exact values, meaning pi is left in the answer, the volume would be:
1/2 diameter = radius --> radius = 15 feet.
Height = 20 feet
V = pi * (15)^2 * 20
V = pi * 4500 ft^3 which is read as 4500pi cubic feet.
One foot of 3 inch pipe will hold approximately 0.625 gallons of water.
0.1631168The value 0.1631168 is the number of US gallons per foot of 2" pipe. The number of gallons per foot of 4" pipe is 0.652798
I will work with the assumption that you mean an 18 inch diameter pipe. The radius (r) is 9 inches and the length (l) is 12 inches per foot. The volume contained will be calculated by ∏r2l = ∏ x 92 x 12. If we use 3.1416 as the value of ∏, that gives us 3.1416 x 81 x 12, which works out at 3,053.6352 cubic inches of water. Now, an Imperial gallon and a US gallon are different - an Imperial gallon holds 277.42 cubic inches and a US gallon holds 231 cubic inches So in Imperial gallons the 12 inches of pipe holds 3,053.6352 / 277.42 = 11.0072 gallons and in US gallons it holds 3,053.6352 / 231 = 13.2192 gallons.
One gallon of water equates to 231 cubic inches.There are 231 cubic inches in one gallon of water.
There is 1.5 gallons per foot in 6" pipe and 2.59 gallons in 8" pipe, so I would think there should be about 2 gallons per foot in 7" pipe.bob... 1.998 gallon Pi x R Sq x L (12") divided by 231 as there are 231 " in a gallon(pie)2.14R^2 * L / 27 all must be in the same units (ft. is best)you get a (cu ft) answer h20 is 7.5 gal per cu ft 7.48 gal per cubic foot which equils 1 fixture unit If your figuring inches you take Pi x R 2 x L divided by 231 as there are 231" in a gallon IF your figuring feet you take Pi x R sq x L x 7.48 as there are 7.48 gallon in a CUBIC foot
A 24-inch diameter cylinder holds 23.5 gallons of water per foot of length/height.
It is 7.83 gallons per inch. .785x4x4x1=12.56 cubic feet. 12.56 cubic feet x 7.48 gallons per cubic foot=93.9 gallons per foot 93.9 gallons per foot / 12 inches per foot =7.83 gallons per inch.
A 4-inch diameter cylinder holds 0.7 gallons per foot of depth.
The cylinder holds up to 7,943.23 gallons of water.
One foot of 3 inch pipe will hold approximately 0.625 gallons of water.
1.15 gallons of water.
615,142 gallons of water are needed to fill this cylinder.
This cylinder will hold up to 19.65 gallons of water.
A 5-inch pipe will hold approximately 0.36 gallons of water per linear foot. This calculation is based on the formula for calculating the volume of a cylinder (V = πr^2h), where the radius (r) is half the diameter of the pipe (2.5 inches) and the height (h) is 1 foot.
21.76 US gallons of water.
The volume of water in a 4-inch diameter, 1-foot section of pipe is 0.6528 gallons of water.
Assuming the dimensions given are inside dimensions, the cylinder will hold 55.75 gallons - less if the dimensions given are outside dimensions.
