Figure 13.
The plot marks alpha equals 0.05 and n equals 1, 10, 20, 30, 50. The horizontal axis is xi and ranges from 0.0 to 2.0. The vertical axis is R e raised to 1 over 2 C f and ranges from minus 5 to 40. The curves start near 0 at xi 0.0 and increase as xi increases. The curves stay close at first, then oscillate more clearly after xi about 0.4. The oscillations become larger and more frequent toward xi 2.0. The highest values occur near xi 2.0. An arrow points from the n values toward the lower part of the curve group near xi about 0.6.Impact of n on when = 0.05
