Water Calculators
Practical starting tools for volume, flow and turnover discussions. Final equipment selection still requires verified dimensions, pump curves, pressure, head loss and water-quality review.

Single-Pass Turnover Time
Ideal mathematical turnover10.00 hoursReal mixing and treatment performance depend on hydraulics, dead zones and operating conditions.
Calculations Are a Starting Point—not a System Design
Confirm actual flow
Pump flow changes with total dynamic head, piping, valves, manifolds and nozzle pressure.
Use average depth carefully
Irregular ponds and reservoirs need bathymetry or a defensible volume estimate.
Define the treatment objective
Turnover alone does not determine oxygen demand, gas transfer, algae coverage or process performance.
