##### On the flow between two rotating coaxial disks ...

The steady motion of a viscous fluid confined between two coaxial rotating disks is discussed both experimentally and theoretically. It is found experimentally that when the disks rotate in the same sense the main body of the fluid rotates as well, but if they rotate in opposite senses the main body of the fluid is almost at rest. An adequate theory is found to explain this.

##### Puzzling : Relative motion of two points on a rotating disc

But it does rotate, if your reference frame does not rotate, but just gets centered on your point of interest. If you want to consider a rotating reference frame, then all points (that are fixed to the disc, or to the frame) are obviously and by definition stationary inside it, and there is no "relative motion" between them in such a reference frame.

Each and every point of the disk will have same angular momentum. But linear velocity varies. we know that Linear velocity = Radius * Angular velocity.

Thus due to same angular velocity of points A&B,Point B will rotate with more linear ...
