Duct Diameter Sizing Charts The following is needed to determine the duct diameter: CFM and Velocity (CFM / V = AREA). In geometry, an ellipse is a regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant, or resulting when a cone is cut by an oblique plane that does This calculator is designed to give the approximate circumference of any ellipse. Flat Oval has many advantages over rectangular duct: better airflow, lighter weight, longer lengths, rapid availability, easy to adjust to length and easier to install
