5.5. Flow Classifications

Try these first

1. 1.

   What is one-dimensional flow?

   Hint

   Think about flow in a straight pipe.

2. 2.

   Define turbulent flow.

   Hint

   Visualize the chaos in stormy weather.

3. 3.

   What characterizes one-dimensional flow?

   • Velocity is constant
   • Changes in one direction
   • Chaotic motion

   Hint

   Think of water flowing strictly along a pipe.

4. 4.

   True or False: In turbulent flow, fluid particles follow orderly paths.

   • True
   • False

   Hint

   Consider how water behaves in a turbulent river.

5. 5.

   A water pipe has a known diameter and a turbulent flow. If the water’s velocity fluctuates, how would you calculate the average flow rate?

   Hint

   Flow rate is area times velocity.

6. 6.

   In a tank with steady flow entering and exiting, how would you determine if the flow is uniform?

   Hint

   Remember the definitions of uniform and steady flow.
