eng.sedimentation-basin-design Calculator
Calculates sedimentation basin surface area from design flow, overflow rate, and particle settling velocity using Stokes' law and Camp's basin theory. Overflow rate (Q/A) is the critical design parameter — particles with settling velocity greater than the overflow rate will be captured regardless of basin depth.
Inputs
Flow M3 Day
Reference formula or conversion factor shown for context.
Surface Overflow Rate M Day
Volume of fluid per unit time. Used to size pipes, pumps, and ducts.
Detention Time Hr
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Particle Settling Mm S
Speed in a specified direction (m/s). Required for momentum, kinetic energy, and wave calculations.
Results
basin surface area (m²)
The computed two-dimensional surface area.
basin volume (m³)
The computed three-dimensional volume.
basin depth (m)
The computed depth.
overflow rate (m³/m²·day)
The value at the specified point or condition.
removal efficiency estimate
Useful output divided by total input, as a percentage. True 100% efficiency is impossible — losses appear as heat. LEDs: 30–50%. Electric motors: 85–97%. Switching supplies: 85–95%.
SOR = Q/A
