2016-4-9  Losses in Elbows and Fittings. When an air stream undergoes change of either direction or velocity, a dynamic loss occurs. Unlike friction losses in straight duct, fi tting losses are due to internal turbulance rather than skin friction. Hence rough-ness of material has but slight effect over a wide range of moderately smooth materials.
