You can Change the RED Cells and the Speed or the RPM Will Change Automatically.
For practical reasons, the figures are rounded to the nearest multiple of 50 rpm.

If you want to know the Speed at a certain RPM, change this Figure: 4,150 4th 52
5th 62
While rounding to the closest 50rpm is considered adequate, if you want to know the Exact Figures, remove "MROUND(" from the beginning of the formulas and ",50)" from the end.
You MUST Install the Excel Analysis Toolpak to Run this Function. Tools, Addins, Check "AnalysisToolpak"
