1. Pipe flow

Try these first

1. 1.

   Define pipe flow.

   Hint

   Remember, fluid types can vary!

2. 2.

   What is the maximum Reynolds number for laminar flow?

   Hint

   Think about the critical range for laminar behavior.

3. 3.

   What is the primary driving force in pipe flow?

   • Gravity
   • Pressure Gradient
   • Friction

   Hint

   Think about what pushes the fluid through the pipe.

4. 4.

   True or False: In laminar flow, the fluid moves chaotically.

   • True
   • False

   Hint

   Consider how laminar flow appears compared to turbulent flow.

5. 5.

   A water system uses a pipe of radius 0.025 m with a length of 10 m. Given a pressure difference of 500 Pa and a viscosity of 0.001 Pa·s, determine the flow rate through the pipe.

   Hint

   You need to work out using the flow rate equation specific to pipe flow.

6. 6.

   If a DIY project requires moving 100 liters of water through a pipe in a controlled laminar flow, how long will it take if the Reynolds number is maintained at 1500?

   Hint

   Remember the concepts of flow rates and convert all units to meters and seconds.
