6. Fluid Flow Problems

Try these first

1. 1.

   What is a velocity field?

   Hint

   Think about the components that represent direction.

2. 2.

   Define streamline.

   Hint

   Consider how they relate to the direction of flow.

3. 3.

   What is the primary purpose of analyzing fluid flow?

   • To visualize the flow
   • To determine pressure distribution
   • To create color patterns

   Hint

   Think about what drives fluid movement.

4. 4.

   True or False: Streamlines, pathlines, and streaklines are identical in steady flow.

   • True
   • False

   Hint

   Consider how time affects these lines.

5. 5.

   A fluid flows through a pipe with varying diameters. Predict how the velocity change relates to the pressure change throughout the pipe.

   Hint

   Consider the conservation of energy in fluid flow.

6. 6.

   How might one experiment with temperature gradients to analyze their effect on fluid density in motion?

   Hint

   Think about how heat rises in water and impacts flow.
