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.

1.) An electric motor can accelerate a Ferris wheel of moment of inertia I = 19500 kg·m2 from rest to 10.1 rev/min in 12.0 s. When the motor is turned off, friction causes the wheel to slow down from 10.1 to 8.1 rev/min in 10.0 s. (a) Determine the torque generated by the motor to bring the wheel to 10.1 rev/min. (b) Determine the power that would be needed to maintain this rotational speed. W 2.)A disk-shaped merry-go-round of radius...
