1. The problem statement, all variables and given/known data A Centrifuge rotates at 12000rpm. What is this in radians per second? If the radius of this centrifuge is 150mm, what is the centripetal acceleration? 2. Relevant equations v2 / r v = rω a = rω2 3. The attempt at a solution First I converted the 12000rpm to 1256.64 rad/sec. 12000 / 60 = 200 Rev. per minute. 200 x 2∏ = 1256. 64 rad/sec Onto the centripetal acceleration, I was given a = rω2 a = 0.15 x 1256.642 a= 236871.61 m/s2 I'm just a little thrown off by how incredibly large the number is and I don't really have any idea of how a centrifuge usually moves. Any help? Would be much appreciated.
