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)
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.
A 56-inch diameter circle has an area of about 17.06 square feet.
copper pipe has a wall thickness between .032 of an inch and . 308 of an inchinside diameter .811 of an inch to .434volume=pye*(diameter/2) squared*length=3.14*(0.811/2)squared*(20ft*12 inches)= 123.914636 cubic inches123.914636 (cubic inches) = 0.536426993 US gallons
There are 22.85 gallons in a waste line which is 2 inches in diameter and is 140 feet long. This can be calculated as pi * r *r *length *7.48051 where r and length are both expressed in feet. (pi = 3.14159265).
31.987 gallons per foot.
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.
The volume of a 5,000-foot long pipe with a 6-inch diameter is: 981.75 cubic feet.
50 feet of 2.5-inch diameter hose has a volume of: 1.7 cubic feet (12.72 liquid gallons)
It would require 2,937.6 US gallons of water to fill the pipe.
A 59.5-inch diameter cylinder holds 1,733 gallons per inch 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.
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.
