17.1.4. Velocity Distribution in Pipe Flow

Try these first

1. 1.

   What is the definition of incompressible flow?

   Hint

   Think about the conditions on the Mach number.

2. 2.

   How do you calculate volumetric flux?

   Hint

   It relates area to velocity.

3. 3.

   What is the condition for a flow to be classified as incompressible?

   • Ma < 0.5
   • Ma < 0.3
   • No density variation

   Hint

   Remember the threshold for density variances.

4. 4.

   True or False: Volumetric flux can vary based on the area and velocity.

   • True
   • False

   Hint

   Think about the relationship defined by Q = A × V.

5. 5.

   You have a pipe with varying diameter; how can you determine the velocity profile at each section?

   Hint

   Think about how diameter affects both area and subsequent velocity.

6. 6.

   Given a variable density fluid in a pipe with known inflow and outflow, calculate the mass conservation across sections.

   Hint

   Keep in mind the interplay between density and velocity in the incompressible flow assumption.
