angular velocity
A centrifuge is used to increase the sedimentation rate of
particles suspended in a liquid, over the rate produced by gravity alone. Find the angular velocity of a centri - fuge in which a particle 10.0 cm from the axis of rotation experiences a radial acceleration of 1.00* 10^3 times gravitational acceleration g. Solution: radius (r) = 0.01 m ; ar = 1.00*10^3*9.80 1.00*10^3*9.80 = (.01)w^2 w = ( 1.00*10^3*9.80/.01)^(1/2) = 989 Answer is 313 rad/sec.... where did I go wrong>? |

10.0 cm = 0.1 m
Do not underestimate the girth of the centimeter. |
