The volume of water in a pipe depends on its length as well as its diameter. To calculate the volume of water in a 3-inch pipe, you would need to know the length of the pipe as well. Once you have that information, you could use the formula for the volume of a cylinder (πr^2h, where r is the radius of the pipe and h is the length of the pipe) to find the volume in cubic inches, which can then be converted to gallons.
I'll assume you have Schedule 40 pipe. 2.5 inch has an ID of 2.469 inches, and an area of 4.7878 in^2. The volume of 69" of that (5.75 ft) is 330.4 in^3. One gallon is 231 in^3, so it will contain 1.430 gallons if full.
To convert the volume of a pipe in meters to Imperial gallons, you would need to know the cross-sectional area of the pipe as well as its length. Given the inside diameter (ID) of 102 mm, the radius would be 51 mm. Using the formula for the area of a circle (A = π * r^2) and the conversion factor of 1 cubic meter = 219.9692 Imperial gallons, you can calculate the volume and then convert it to Imperial gallons.
The inside diameter (ID) is 8 inches. The nominal pipe size (NPS) and outside diameter (OD) depend on the thickness of the walls of the pipe.
Assuming you're talking inner diameter (ID) of the pipe some basic math will answer this question. Volume of a cylinder = pi * radius^2 * length So for us, pi *.25*.25*12 = 2.35619449 cubic inches = 1.30559695 US fluid ounces. So a better question would be how many oz per foot.
radius squared times pie times length = cubic inches1.5 x 1.5 x 12 = 84.78 cubic inchesThere is 231 cubic inches in a gallon, therefore 84.78 divided by 231 = .36 gallonsThe improved answer is as follows: (the solution above omitted Pi (3.1416)), therefore3.1416 x 1.5 x 1.5 x 12 = 84.82 (carrying Pi out to 4 places) divided by 231 = .367 gallons.The answer was correct, but the solution as shown didn't show Pi as part of the equation
294.12 inches 24.51 feet.
A square foot has no volume. if you are asking how many gallons are in a cubic foot the answer id 7.4805195.
To calculate the capacity of a pipe you need to first calculate the area and volume. So assuming your pipe has an inside dimension (ID) of 3 inches, you would use the following equation. πR2 = area πR2xH = volume π=3.1416 Using inches as our unit R (radius) = half the diameter = 1.5 inches H (height or length of pipe) = one foot of pipe = 12 inches Gives you the volume in cubic inches 1728 cubic inches per cubic foot (12x12x12) One cubic foot = 7.48 US gallons (RxR)x3.1416x12 (1.5x1.5)x3.1416x12 = 84.82 cubic inches 84.82/1728=.049 cubic feet .049 cubic feet x 7.48 US gallons per cubic foot = 0.36652 US gallons per foot of 3" ID pipe.
The ID of a pipe (inner diameter) can be calculated by subtracting the pipe's wall thickness from its outside diameter. The formula is ID = OD - 2*WT, where ID is the inner diameter, OD is the outer diameter, and WT is the wall thickness of the pipe.
Assuming you are dealing with half inch id tubing it is 13.17 cubic cm per inch.
To calculate the volume of water a pipe can hold, we need to use the formula for the volume of a cylinder: V = πr^2h. For an 8-inch diameter PVC pipe that is 10 feet long, the radius would be 4 inches (half of the diameter). Converting the measurements to the same units (inches), the volume would be approximately 2480 cubic inches. Converting this to gallons (1 gallon = 231 cubic inches) gives us approximately 10.7 gallons.
