Flow of Fluids 487
where C, = 1.3 and K = 0 for 8 = 0"
v, = 1.3(11.36) + 0 - 14.768 ft/s
15. Liquid holdup q, Equation 6-95,
=I- 5.48 + ( 1 - 0. 781)( 14.768 - 1 1-36) = o, 578
14.768
16. For 8 = 0", calculate average liquid velocity, v,,
vL = v, 5-88 =
= - lO.l7ft/s
H, 0.578
17. Calculate ReL and fwL from Equation &97b
f*=-= 0.046 0*046 = 3.983~ 10"
R:: (205,564)"*
18. Average slug density yb from Equation 69%
YL, = EJ, + (1 -
= 0.781(53.65) + (1 - 0.7)(10.95)
= 44.3 lb/ft5
19. The fractional pressure gradient from Equation 6-97a
2(3.983 x loJ)( 44. q(10.17)'
(9/12)(32.2)
= -1.51 132
20. The total pressure gradient, since 8 = 0"
