What This Calculator Does
Calculate duct dimensions for room airflow requirements.
It combines Room Square Footage, Room Type, System CFM, Duct Type to estimate Duct Size, Room CFM Required, Air Velocity.
Formula & Method
Notation used in the formulas: R = Duct Size; x_{1} = Room Square Footage; x_{2} = Room Type; x_{3} = System CFM; x_{4} = Duct Type.
Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.
Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
Inputs Used
- Room Square Footage: Used directly in the calculation.
- Room Type: Used directly in the calculation.
- System CFM: Total system CFM (0 to estimate)
- Duct Type: Used directly in the calculation.
