a. Relative Centrifugal Field (RCF) is the ratio of the centrifugal acceleration at a specified radius and speed ( rw
2
) to the standard acceleration of
gravity ( g ) according to the following formula: RCF = r  /g — where r is the radius in millimeters,  is the angular velocity in radians per
second (2  RPM /60), and g is the standard acceleration of gravity (9807 mm/s
2
). After substitution: RCF = 1.12r (RPM/1000)
