Important Notes
- Nominal vs. Inside Diameter: For most pipes, the nominal pipe size (e.g., 2") is not equal to the actual inside diameter. The values in the table above are based on the inside diameter. For precise volume calculations, always consult the pipe's documentation or relevant standard (e.g., ANSI Schedule 40).
- Density Compensation: The provided weight values are for water. To calculate the volume weight for other liquids, the values must be compensated for the specific liquid's density.
Practical Example
The water volume in a pipe can be calculated by multiplying the pipe's internal volume per unit length by its total length.
Example: Calculate the water volume in a 12 m long, 2" (nominal) pipe.
Using the table value for a 2" pipe (inside diameter): 2.0 liter/m
