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.
Duct systems are commonly divided into three pressure classifications. Duct Velocity Calculate velocities in circular and rectangular ducts - imperial and SI-units - online calculator. Ductwork - Seal Classes Ductwork air leakage classes. Natural Draft - Air Flow Volume and Velocity ...
