sci.sedimentation-efficiency-Yao Calculator
Calculates sedimentation efficiency of a clarifier from the surface overflow rate and settling velocity using Yao's model: E = 1 − exp(−v_s/SOR). Clarifier design SOR: 30–60 m/day for municipal activated sludge — efficiency drops rapidly for SOR > critical settling velocity.
Inputs
Q M3 Hr
Volume of fluid per unit time. Used to size pipes, pumps, and ducts.
W M
Horizontal extent perpendicular to the length.
L M
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
H M
Vertical extent downward, or thickness of a layer. For tanks: affects pressure at the base (P = ρgh).
Vs Cm S
Speed in a specified direction (m/s). Required for momentum, kinetic energy, and wave calculations.
Results
surface overflow rate SOR (m³/m²·hr)
The value at the specified point or condition.
settling efficiency η
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%.
overflow rate (m/s)
The value at the specified point or condition.
η = vs/SOR (when vs < SOR)
Sample size or count used in the calculation.
design SOR guideline
Sample size or count used in the calculation.
