  • Average flow velocity
  • Instantaneous local velocity
  • Frictional velocity

💡 Hint: Think about how local conditions differ in a turbulent flow.

Question 2

True or False: The difference in velocity at a point is the same for both smooth and rough pipes.

  • True
  • False

💡 Hint: Reflect on the key findings from our equations on velocity.

Challenge Problems

Push your limits with challenges.

Question 1

Given a turbulent flow with a measured maximum velocity of 8 m/s and a frictional velocity of 3 m/s, determine the difference in velocity at 0.25 m from the wall of a pipe with radius 1 m. Use the derived logarithmic equation.

💡 Hint: Focus on logarithmic properties when solving.

Question 2

If a power law velocity profile with n = 6 is given, derive an expression for the average velocity considering a pipe with radius R and radius r. Explain your steps.

💡 Hint: Break down each step starting from the power law equation to simplifying the integral.
