For the triangular duct shown in Fig. P10.24 , obtain the constant C , which relates the Fanning friction factor f to the Reynolds number R e as f = C / R e . Use triangular finite elements. Verify the answer by refining the finite element model. Compare the results for C with that to a square duct having the same perimeter.
