How to use this Nomograph:
1.  You can get centrifugal force (RCF) with line connection between rotation radius (cm) and speed (rpm).
2.  You can get speed (rpm) with line connection between rotation radius (cm) and centrifugal force (RCF).

Calculating Centrifugal Force:
RCF = 11.18 X ( N / 1000 )2 X R
RCF: Centrifugal Force (Xg)
R: Rotation Radius (cm)
N: Speed (rpm)
