Asap
For steady flow of a viscous incompressible fluid
through a circular pipe of constant diameter, the average
velocity in the fully developed region is constant. Which
one of the following statements about the average
velocity in the developing region is TRUE?
A. It increases until the flow is fully developed.
B. It is constant and is equal to the average velocity in
the fully developed region.
C. It decreases until the flow is fully developed.
D. It is constant but always lower than the average
velocity in the fully developed region.
