12.7: Centrifugal Force
The centrifugal force was defined as. Fcf = −mω × (ω ×r′mov) (12.7.1) (12.7.1) F c f = − m ω × ( ω × r m o v ′) Note that. ω ⋅Fcf = 0 (12.7.2) (12.7.2) ω ⋅ F c f = 0. therefore the centrifugal force is perpendicular to the axis of rotation. Using the vector identity, equation 19.2.25 19.2.25 allows the centrifugal force to ...

force across its height. As each coal particle enters the rotor, it is acted upon by two oppos- ing forces. The aerodynamic force of the transport air acts to "push" the coal particle through the rotor. At the same time, the rotation of the rotor imparts a centrifugal force on the coal particle in the opposite (outward) direction.

Operating and Maintenance Guidelines for Screenbowl Centrifuges
Centrifugal force, which is the outward force acting on a body rotating about an axis, is dependent upon the rotational speed of the machine. For convenience, centrifugal force is usually reported as the number of earth gravities (i.e., number of Gs) pulling a particle away from its rotational centerline. The number of Gs can be calculated …
