4. Operation 

4.5 Calculating Relative Centrifugal Force (RCF) 

An RCF can be determined by calculation or by referring to the graph provided below.   
The rotating radius of each rotor is given in the rotor instruction manual. 

  Calculation formula: RCF = 1,118 x Rotating radius (cm) x Rotating speed 

2

 (rpm) x 10

-8

 

Calculation  graph  is  shown  below.  The  point  of  intersection  between  the  rotating 
radius and the speed indicates the corresponding RCF.   
The example shows an RCF of 1,500xg with a rotating radius of 15 cm and a speed of 
3,000 rpm.
