Line Pipe Unit Mass And Weight

Calculate pipe unit mass (mass per length), unit weight (weight per length), and total mass from pipe schedule diameter and wall thickness.

Use the Result Table option to display the results for the selected pipe diameter. For multi layer pipes (line pipe with outside layers and or inside layers), the results for each layer are displayed in the output view at the bottom of the page. Change the number of layers on the setup page.
