22.7.2. Velocity Profile for Turbulent Flow

Try these first

1. 1.

   Define turbulent flow.

   Hint

   Recall the opposite flow type.

2. 2.

   What is the purpose of the Moody diagram?

   Hint

   Think about energy losses.

3. 3.

   What is the primary characteristic of turbulent flow?

   • Smooth and orderly
   • Chaotic and irregular
   • Linear

   Hint

   Think about the opposite of turbulent flow.

4. 4.

   The Moody diagram is used to assess?

   • True
   • False

   Hint

   Is it related to energy losses in pipes?

5. 5.

   Determine the turbulence regime of a given flow with Reynolds number 2500. Explain your reasoning.

   Hint

   Refer to definitions and the Reynolds number guide.

6. 6.

   Calculate and analyze wall shear stress for a flow with a velocity of 3 m/s in a circular pipe of diameter 0.1m.

   Hint

   Remember the factors that affect shear stress along the wall.
