very common friction rate for a reasonably well designed system is 0.1 in.-wc per 100 ft. of duct length. Reducedfriction rate s of 0.05 in.-wc per 100 ft. increases the duct size and costs by 15%, but cuts the portion of the total pressure drop in ductwork by 50%, resulting in fan energy savings of 15% to 20%.

https://li-hvac.com/wp-content/uploads/2022/07/Air-Leakage-in-Ductwork_2021.pdf
It is interesting to note that with all ductwork now having the same Leakage Class requirement, it is permissible to have more air leakage from rectangular ductwork than round ductwork. For example, 24-inch diameter round duct has a surface area of 6.28 square feet per linear foot of duct and an equivalent size

Class 3 Leakage even at 10 in. wg static pressures. Flat Oval is the next most efficient shape and the closer the aspect ratio approaches 1, the more it approaches the efficiency of round duct. An aspect ratio of 1 is round duct. When a designer sees rectangular duct on a drawing, they should convert it to an equivalent round size if possible.

From the friction loss chart or Equation 1.6, find the pressure loss per 100 feet for 3,000 cfm flowing through a 20-inch diameter duct. This value is 0.14 inches wg, or. 0.70 inches wg for 500 feet. Similarly, the friction loss for 500 feet of 16-inch diameter duct carrying 3,000 cfm is found to be 1.95 inches wg.
