# Long description

The figure is a graph of C D (C underscore D) on the vertical axis against Re on the horizontal axis. The vertical scale is logarithmic from 10 to the power of minus 1 to 10 to the power of 2. The vertical scale is logarithmic from 10 to the power of minus 1 to 10 to the power of 7. The graph decreases from the vertical axis following a curve with decreasing gradient to a plateau, then increases a little, then a sharp fall (a notch) and a steady rise at the end. Approximate values are as follows:

## Table 6

Re | C subscript D | Comment
--- | --- | ---
0.01 | 60 | At vertical axis
1 | 10 | Decreasing
10 | 3 | Decreasing
100 | 1 | Decreasing
1000 | 1 | Plateauing
10000 | 1.1 | Plateauing but rising a little
1 times 10 to the power of 4 | 1.1 | Rising a little more
3 times 10 to the power of 5 | 1.1, falling to about 0.5 | Point where rapid decline starts
10 to the power of 7 | 1 | Final point
