Pipe Flow

Pipe flow content connects velocity, friction, roughness, pressure loss, head loss, and practical unit choices.

Core pipe-flow paths

Choose a calculator first, then use the linked references to check assumptions and interpretation.

Pipe velocity

Compute average velocity from flow rate and pipe diameter.

gpmdiameter

Darcy-Weisbach pressure loss

Estimate pressure loss with visible friction and roughness assumptions.

dphead loss

Pipe flow continuity

Review the continuity equation and where average velocity applies.
