Centrifugal force Centrifugal force (F) centrifugal force as the real power simply do not exist in non-inertial reference frame in order to facilitate the calculation of an imaginary force. Please look at the following: objects so that the centripetal force by one point to the center of the attraction or repulsion or any inclined to the point. Descartes as centrifugal force to object to maintain its "limited quantity" of a trend. Their difference is, is the centripetal force of the inertial reference system under, and the centrifugal force of non-inertial force. We have to deal with the physical problem when they were under the inertial system (Newton's Law was set up only at this time), so in general do not have the concept of centrifugal force. As the case is not a concept, we can not on their size and direction of the comparison.

F = mω2r

ω: spin angular velocity (radians / sec) r: spin-off from the axis of rotation (cm) m: particle mass

Relative centrifugal force Relative centrifugal force (RCF)

RCF is the centrifugal force into a real multiple of the acceleration due to gravity

g for the acceleration due to gravity (9.80665m/s2)

With the turn in the rotation for a week equal to 2π arc, the angular velocity of the rotor to spin the number of times per minute (RPM n or r / min): Under normal circumstances, often in low-speed centrifuge r / min to that.

3, the separation factor formula:

RCF = F centrifugal force / F gravity = mω? 2r/mg = ω? 2r / g = (2 * π * r / r * rpm)? 2 * r / g Note: rpm should be changed to break / s

For example: the diameter of 1000mm, speed to 1000 / centrifuges, the separation of factors:

RCF (1000) = (2 * 3.1415 * 16.667) ^ 2 * 0.5/9.8

104.72 * ^ 2 = 0.5/9.8  =560
