Question

This is a multi-part question. Once an answer is submitted, you will be unable to return to this part As steam is slowly injected into a turbine, the angular acceleration of the rotor is observed to increase linearly with the time t Know that the rotor starts from rest at t = 0 and that after 10 s the rotor has completed 20 revolutions.

Determine the angular velocity at t20 s. (You must provide an answer before moving on to the next part)


The angular velocity is [ ] rpm.

Answer 1

60 rpm

Step-by-step explanation:

At t = 0,

Angular speed = 0

At t = 10 sec

Angular speed = 20/10 = 2 rev/s

Average speed = (2 - 0)/2 = 1 rev/s

= 1 x 60 = 60 rpm
