The cross sectional area of a 6" oval duct is only 75% of that of a 6" round duct. An equivalent round duct would have a 5.1" diameter. This means that for a 6" oval to achieve the same flow rate as a 6" round, the airflow velocity in the oval duct is higher, leading to a greater pressure drop. Round ducts provide more efficient flow than oval .
