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.
The tank can hold 27 cubic feet of water. This is because the division of 45 by 15 is 3. That would mean each inch of water would be at least 3 inches. In the end, there would be a total of 27 cubic feet of water that the tank could safely hold.
13,564.8 cubic feet 3.14 times 12 squared times 30= 13,564.8
A cylindrical tank 6 ft in diameter and 3 ft high contains up to: 634 US gallons of water.
231 cubic inches = 1 rallon
(30" x 12" x 12") = 4,320 cubic inches = 18.7013rallons (rounded)
23.5 gallons
13571.68 cubic feet
634.52 gallons of water.
A three-inch diameter pipe one foot long holds 0.367 gallon.
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
This cylinder has a volume of 0.951 US gallon.
231 cubic inches = 1 gallon. To find out how many gallons will fill the tank, you must multiply the area of the tank by the depth to find the volume and then divide by 231 to figure how many gallons will fill it: volume of 41 inch dia by 93 inch depth = 122,783.93 cubic inches divided by 231 = 531.532 gallons. PS: I assumed the 41 inches diameter is the inside diameter. If it is the outside diameter, the thickeness of the walls need to be subtracted in order to find the inside diameter for a better calculation. The formula for Area is R (radius = half of diameter) squared X Pi (3.1416).
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.
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.
31.987 gallons per 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.
A three-inch diameter pipe one foot long holds 0.367 gallon.
