Calculator path
- 1 Pipe slope calculator Primary page for the main search intent.
- 2 Pipe slope formula Supporting formula or reference page.
- 3 Pipe pressure drop calculator Darcy-Weisbach loss, head and velocity from flow and pipe ID.
- 4 Pipe size by flow velocity pick a first-pass pipe ID from flow and target velocity.
- 5 Pump flow and HP calculator pump displacement, pressure, flow, kW and horsepower.
Fall
fall = run * slope_percent / 100
Pitch ratio
ratio = run / fall
Invert elevation
end_invert = start_invert - fall
