A duct size calculator, commonly known as a ductulator, depends on factors like the size of the space you’re heating or cooling, air flow velocity, friction loss, and available static pressure of the HVAC system.
Move the sliders for Airflow, Duct Diameter, Width and Height up and down to match the desired duct size to calculate velocity and pressure drop for. The Diameter, Width and Height will change such that the equivalent size is shown:
Using a predefined static pressure loss per unit of duct length, DuctCalc.Ca Ductulator App calculates the diameter of round duct and the other dimension of rectangular duct. Based on the calculated dimensions, the air velocity will be calculated for both duct shapes and dimensions. Velocity Met...
These are properly-termed resistance to air flow or SP or Static Pressure. Kitchen and bath exhaust fan manufacturers give duct sizing charts for various air flow requirements, such as this EXHAUST DUCT VENT FAN SIZING CHART [PDF] from CaptiveAir Products, 4641 Paragon Park Road Raleigh, NC ...
