Figure 2-21. Friction factor for flow in pipes [l].

D = 2A/C = 0.0833 ft
v = Q/A = [(1,000 gal/min)(0.1337 fts/ga1)/(60 s/min)]
= .0278 ft' = 80.21 ft/s
= 7,380 x lb-s/ft2 @ 32°F
= 647 x Ib-s/ft' @ 104°F
g = 32.2 ft/s2

At 32°F

(56.60)( 0.0833)( 80.21) = 1, 59
R=
(32.2)(7,380x lod)
Because R < 2,000 the flow is laminar and f = 64/R = 0.04022. Assuming that the fluid is
incompressible implies that yl = y, and v1 = v2, and Equation 2-54 can be rewritten as

(0.04022)( 100)(80.21)' 1
2( 32.2)( 0.0833)
