Summary

Effects of roughness, size, and constructional features on efficiency and pressure loss are checked in two intake ducts of different area. Results indicate that larger internal passages increase efficiency. Poor finishing may decrease efficiency by as much as 50%, while spoilers may increase duct pressure los by 700%. Splitter vanes across duct, to insure rigidity, increase pressure loss by about 50%.
