Final answer:
It is true that the center moves faster than the outer edges in a flow, as frictional forces at the boundaries slow down the fluid near the edges more than at the center.
Step-by-step explanation:
The statement that in a flow, the center moves faster than the outer edges is true. This phenomenon occurs due to the effect of viscosity and frictional forces present at the boundary of the flow, which are in contact with the pipe or any surface the fluid is flowing through. An example of this can be seen with the flow of water in a river; the water at the center moves faster than that near the shores due to less resistance and turbulence.
When it comes to angular and linear velocities, both points on a rotating disk or flow have the same angular velocity, while the point near the outer edge has the higher linear velocity due to its greater distance from the center.
