Centifugal field The ang angular velocity of a rigid body that rotata about a fixed axis is defined as the ratio of the angular displacement in a given time. Interval. One radian, abbreviated as I rad, represents the angle Subtended at the centre of a circle. It is equal to the length of an arc with a to the radius of the circle. Sinu 360° equals 2 radians, one revolution of the rotor can be expressed as a rad | revolution = 2 = 2 radians = 360° The sedimentation rate depends upon the applied centrifugal field (Um52) G. πη The Centrifugal fuld is determined by the radial distane (1) of the particle. from the axes of rotas (in cm) and the square of angulas velocity (00) of t Motor (in radian per seund). G=wr. →The rotor angular velocity, in rads per seconds of the can be expressed in terms of W=215/60. rotor speed, s (in "the Centrifugal field can be expressed ar. 2 G=/2115) 60 G=411² (rovmin')'r = 413 2 2. 3600 3600 Min- →Multiply by 60
