Question 1

What does the One-Seventh Power Law approximately describe?

  • Velocity profile in laminar flow
  • Velocity profile in turbulent flow
  • Pressure distribution in a pipe

💡 Hint: Think about where turbulence is most relevant.

Question 2

True or False: Displacement thickness pertains to the lost mass flow in a boundary layer.

  • True
  • False

💡 Hint: Consider how layers of fluid alter flow characteristics.

Challenge Problems

Push your limits with challenges.

Question 1

Given a flat plate in a turbulent flow, calculate the displacement thickness if the free stream velocity is 10 m/s at a point where the velocity profile shows 7 m/s at a distance of 0.5 m from the plate. Assume necessary values for Kinematic viscosity.

💡 Hint: Remember to account for the velocity deficit in your formula.

Question 2

Explore how changing the surface roughness of an object affects the boundary layer characteristics and the applicability of the One-Seventh Power Law.

💡 Hint: Think about how rough surfaces influence flow dynamics and behavior.
