Solution:

Within a boundary layer for a steady incompressible flow, the Bernoulli equation:

holds because the flow is steady

holds because the flow is incompressible

holds because the flow is transitional

does not hold because the flow is frictional

Solution:

Solution:

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?

It increases until the flow is fully developed.

It is constant and is equal to the average velocity in the fully developed region

It decreases until the flow is fully developed.

It is constant but always lower than the average velocity in the fully developed region.
