FIGURE C-10 Friction factor for staggered tube arrangement<br />

Figure C-9 and C-10 show the friction factor f for in-line arrangement with<br />

square tube and staggered arrangement with equilateral triangular tube. In theses<br />

figures x T = S T /D, x L = S L /D, and x D = S’ L /D denote, respectively, the dimensionless<br />

transverse pitch, longitudinal pitch, and diagonal pitch. Reynolds numbers are<br />

increasing, friction factor will be decrease because pressure drop are increased.
