HVAC Duct Sizing Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
ಸೂತ್ರ
Duct Area = CFM / (FPM velocity) where FPM = 700-900 for mains
ಹಂತ-ಹಂತದ ಮಾರ್ಗದರ್ಶಿ
- 1Calculate required CFM per room, size duct for target velocity
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
Worked Examples
ಇನ್ಪುಟ್
400 CFM, 800 FPM target
ಫಲಿತಾಂಶ
Area = 400/800 = 0.5 sf → 8×9 inch duct
Common Mistakes to Avoid
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
