Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What flow regime is indicated by a Reynolds number above 4000?

💡 Hint: Think about the range provided for laminar and turbulent flow.

Question 2

Easy

In turbulent flow, how does velocity behave close to the pipe wall?

💡 Hint: Consider the effect of viscosity and adhesion to the wall.

Question 1

What is the threshold Reynolds number indicating turbulent flow?

  • 1000
  • 2000
  • 4000

💡 Hint: Recall the commonly accepted values for laminar versus turbulent transitions.

Question 2

True or False: The velocity in a turbulent flow at the wall is always positive.

  • True
  • False

💡 Hint: Consider what happens at the boundary where the fluid meets the wall.

Challenge Problems

Push your limits with challenges.

Question 1

A cylindrical pipe of diameter 10 cm has turbulent flow with a velocity at 1 cm from the wall being 40% more than at 4 cm. Calculate the roughness height using Nikuradse's findings.

💡 Hint: Set up equations based on velocity differences at the specified distances.

Question 2

Given a fluid with properties leading to a Reynolds number of 2500, convert the conditions to exhibit turbulent flow by altering the velocity or viscosity. What adjustments would lead to this change?

💡 Hint: Use the formula for Reynolds number: Re = (Density * Velocity * Diameter) / Viscosity.
