A centrifuge motor provides 746 W and all energy can be assumed by going to accelerate the centrifuge ring, which is a hollow cylinder with inner diameter = 20 cm, outer diameter = 24 cm and a weight of 1.5 kg What is the kinetic energy of the centrifuge ring after 8 seconds?

What is the rotational speed of the centrifuge ring, in revolutions per second, after 12 seconds?

Solutions

Expert Solution

We apply conservation of energy theorem.Here as the entire energy is used the rotate the centrifugal pump we can directly say that the power is comlletely consumed to increase the kinetic energy.
