feet used and then multiply by Equivalent Length shown.
Calculating Duct Length Table
For maximum eciency, use the shortest and straightest duct possible. Use as few ttings as
possible. For best performance, the duct run should not exceed 100 feet of equivalent length.
Calculations are approximate and based on HVAC industry standards.
