Assuming the 6 inch diameter is the inside diameter (otherwise you have to know the thickness of the pipe walls).
Volume = pi * r2 *length
Volume = 3.14159 * 9 * (225*12) cubic inches
Volume = 76 340.637 cubic inches
Convert this to gallons = 330.478948 US gallons
Answer 330.5 Gallons (answer to one decimal place)
To convert feet of water line to gallons, you need the volume of the water line. The volume of a 2-inch diameter water line is about 0.0107 gallons per foot. So, 1000 feet of 2-inch water line would be approximately 10.7 gallons.
A 56-inch diameter circle has an area of about 17.06 square feet.
The volume of a cylinder is (pi ) R2 L.R = 1/2 diameter = 15 inchesL = 25 feet = 300 inches1 gallon = 231 cubic inchesVolume in gallons = (pi) R2 L / 231 = 917.998gallons (rounded)
To calculate the volume of water in a pipe, first convert the diameter to feet (28 inches = 2.33 feet). Then use the formula for the volume of a cylinder (V = πr^2h) where r = radius (half the diameter) and h = height. For a 2.33-foot diameter pipe and 1 foot height, the volume is roughly 17.19 gallons of water per foot.
3 inch (inside diameter) pipe = 0.25 feet. Radius = 0.125 ft Cross section area = pi*(0.125 ft)2 = pi * 0.015625 ft2 . Multiply by 80 ft = pi * 1.25 cubic feet = 3.926990817 cubic feet x 7.480517578 (US gallons / cubic ft) = 29.37592384 US gallons.
Approx 642665 US gallons.
615,142 gallons of water are needed to fill this cylinder.
An 18-inch pipe (inside diameter) 3,000 feet long could hold up to 5,301.44 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
45.9 US gallons.
50 feet of 2.5-inch diameter hose has a volume of: 1.7 cubic feet (12.72 liquid gallons)
The volume of a 5,000-foot long pipe with a 6-inch diameter is: 981.75 cubic feet.
A 59.5-inch diameter cylinder holds 1,733 gallons per inch of length/height.
It would require 2,937.6 US gallons of water to fill the pipe.
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.
The volume of an 8-inch diameter pipe with a length of 1,000 feet is: 349.07 cubic feet (about 2,611.2 US gallons).
The volume is 31.809 cubic feet.
