19.3. Type of Flow

Try these first

1. 1.

   Define laminar flow.

   Hint

   Think of how water flows in a straight pipe without obstacles.

2. 2.

   What is the Reynolds number used for?

   Hint

   It helps determine if the flow is laminar or turbulent.

3. 3.

   What is the maximum Reynolds number for laminar flow?

   • 2000
   • 2300
   • 2500

   Hint

   Think of the threshold for flow classification.

4. 4.

   True or False: Major losses are greater than minor losses in all pipe flow scenarios.

   • True
   • False

   Hint

   If there are many fittings, this may change.

5. 5.

   In a water distribution system, if the Reynolds number in a segment is measured at 1500, explain the expected characteristics of the flow and its implications for energy loss.

   Hint

   Think about how the flow behavior affects pipe design.

6. 6.

   Given a pipe with considerable minor losses because of numerous bends, describe one possible solution to minimize energy dissipation within the system.

   Hint

   Consider how altering the physical setup could change the flow characteristics.
