• Column A (120) = 0 material
• Column B (170) = 0 material
• Column C (240) = 5% of 240 equals 12
• Column D (340) = 90% of 340 equals 306
• Column E (400>) = 5% of 400 equals 20
• Total: 12+306+20 = 338 as average SGN
Figure 7
Using the above crush strength example of 3.5 and average SGN size of 338, we can now use the chart to determine
our maximum spread width. In this case a maximum spinner speed of 650-700 RPM will produce a spread width of
85' to 100' depending on spinner height.
