Calculation method
Calculation method
Total face area (m²)
Sum parallel filter face areas; divide airflow by that total area.
Mean face velocity (m/s)
Sum parallel filter face areas; divide airflow by that total area.
Symbols and units
- a
- Filter width (mm)
- b
- Filter height (mm)
- c
- Parallel filters (count)
- d
- Total airflow (m³/s)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Sum parallel filter face areas; divide airflow by that total area. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
