Figure 17.
The horizontal axis gives xi from 0 to 4, and the vertical axis gives Reynolds number to power one half times C f from about 6 to 24. The curves for S 3, 3.7, 4.9, 5.7, and 8.6 oscillate across xi. They first decrease to about 8 near xi 0.35, then rise to repeated peaks near 23 to 24. Higher S values give slightly higher values across most of the range.Impact of Sphericities on
