To find the volume of a pipe, you can use the formula for the volume of a cylinder: V = πr^2h, where r is the radius and h is the height of the cylinder. For a 2-inch diameter pipe, the radius is 1 inch. Thus, the volume of 12 inches of 2-inch pipe would be π * 1^2 * 12 = 12π cubic inches.
To find the volume of water in the pipe, you would first calculate the cross-sectional area of the pipe (π * r^2, where r is the radius). Then, multiply the cross-sectional area by the length of the pipe to get the volume. Make sure to convert the measurements to the same units (e.g., inches to cubic inches) for accurate results.
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.
To calculate the volume of water in a pipe, you need to use the formula for the volume of a cylinder, which is V = πr^2h, where V is the volume, r is the radius, and h is the height (or length in this case) of the cylinder. In this case, the radius is half of the diameter, so the radius would be 2 inches. Converting the length to inches, we have h = 120 inches. Plugging these values into the formula, we get V = π(2^2)(120) = 480π cubic inches. This is approximately 1507.96 cubic inches of water in a 4-inch pipe that is 10 feet long.
The volume of a pipe is proportional to the square of its diameter. Since the diameter of the 8-inch pipe is twice that of the 4-inch pipe, the 8-inch pipe can carry four times the volume of the 4-inch pipe.
To find the volume of water in the pipe, we need to calculate the volume of a cylinder. The formula is Volume = πr^2h, where r is the radius (half the diameter) and h is the height (length of the pipe). The radius of a 4-inch pipe is 2 inches (1/6.947 feet), so the volume of water in the pipe is about 18.84 cubic feet. To convert cubic feet to gallons, multiply by 7.48, resulting in approximately 140.72 gallons of water in the pipe.
