Pipes & Pipelines
Conveyance elements sized to carry a design flow with an acceptable velocity and friction loss. Internal bore diameter, roughness, and the pressure rating of the pipe material govern hydraulic and mechanical performance.
Engineering Application
Pressure and gravity pipelines for water supply, distribution, process, and drainage. Velocity should stay within self-cleansing and erosion limits, and friction loss calculations (Hazen–Williams or Darcy–Weisbach) feed pump-head and energy estimates.
Key Parameters

| Internal diameter | mm |
