Well first remember that volume is area times height. So first think about what the area of a cross-section of a pipe would be. The cross section would be a circle, and we know the circle is 3 inches in diameter. So use the formula for area of a circle (pi times the radius squared) and multiply that by the length of the pipe. Remember that the radius is half the diameter. Still need help?
assuming that "1 inch" means the inner diameter,
r = 0.5 inches
volume = (pi x r2) x 12 inches [I converted feet to inches to keep the units the same]
volume = 9.42 cubic inches
If the outer diameter is one inch, subtract the thickness of the pipe from 0.5 and recalculate
9.425 cubic inches or 0.0408 gallons of liquid.
V = 1.473 ft3
0.88357 cubic feet.
Volume = 0.8727 cubic feet OR 1,508 cubic inches.
If the pipe is round, with a 55-foot diameter, and 36 inches long, then its capacity is 53,317.3 gallons. If the pipe is round, with a 36-inch diameter, and 55 feet long, then its capacity is 2,908.2 gallons. Either way, we have no way of knowing how much water is in it. For all we know, it may even be empty.
Volume of a cylinder = (pi) (radius)2 (length)Radius = 1/2 (diameter) = 12 inches = 1 footVolume = (pi) (1)2 (50) = 50 pi = 157.1 cubic feet = 1,175 gallons (rounded)That's the volume of the pipe. We have no way of knowing how much wateris in it. It could even be empty.
Completely filled, (pi x radius squared x length in inches)/231 cu in per gallon = gallons = 13.06122449, if the inside diameter of the pipe is 2 inches. =========== Of course that assumes that the inside diameter is exactly 2 inches. For real pipes, the actual inside diameter of a pipe depends on the "schedule" of the pipe. For a "nominal" pipe diameter of 2 inches, the outside diameter will be 2.375 inches and the wall thickness could vary from .065 inches (schedule 5) to .343 inches (schedule 160) meaning that the actual inside diameter could vary from 2.245 inches to 1.689 inches.
The volume of a cylinder with a 2 diameter that is 12 feet long is 37.7 cubic feet.
A 14-inch diameter by 20 foot long pipe has a volume of: 21.38 cubic feet.
A 1,850-foot long pipe with a 16-inch inside diameter has a volume of 2,580 cubic feet. In terms of liquid volume, this section of pipe can hold up to about 19,300 US gallons.
The volume of a 5,000-foot long pipe with a 6-inch diameter is: 981.75 cubic feet.
Volume = pi1210 = 31.416 cubic feet rounded to 3 decimal places
Pipe is generally cylindrical and the dimension refers to the inside diameter. One cubic foot contains 7.48 gallons. The volume of a one foot long 20" diameter pipe is: pi(1.667/2)^2 = 2.18 cubic feet. At 7.48 gallons per cubic foot the total volume is 16.3 gallons.
The volume is 70.685 cubic feet.
The volume of a 100-foot diameter x 200-foot long cylinder is: 11,750,400 US gallons.
A three-inch diameter pipe one foot long holds 0.367 gallon.
Volume = 0.8727 cubic feet OR 1,508 cubic inches.
Assuming cylinder: volume = area of circle * length area of circle = pi*radius**2 radius = circumference/(2*pi) radius = diameter/2 if 24 inch is circumference: volume = pi*(24/(2*pi))**2 * 12 volume = 144/pi*12 volume = 1728/pi inch**3 if 24 inch is diameter: volume = pi*(24/2)**2 * 12 volume = pi*144*12 volume = pi*1728 inch**3 if 24 inch is radius: volume = pi*24**2 * 12 volume = pi*576*12 volume = pi*6912 inch**3 if 24 in
one foot of 2-inch diameter aluminum rod = 22 / 6 = 3.66667 lbs 3.66667 x 15 feet = 55 lbs
The board-foot is a specialized unit of volume for measuring lumber in the United States and Canada. It is the volume of a one foot length of a board one foot wide and one inch thick.
