- A smooth
- steady flow
- Chaotic changes in flow properties
- Linear variation of velocity
💡 Hint: Remember how a lot of currents interact in a fast-moving stream.
Question 2
True or False: The viscous sublayer is where velocity changes significantly.
- True
- False
💡 Hint: Consider what happens right next to the wall.

Challenge Problems
Push your limits with challenges.
Question 1
A pipe with a diameter of 15 cm has surface irregularities of height 0.3 mm. The viscous sublayer thickness is 2 mm. Classify the boundary type.
💡 Hint: Ratio calculations are key to solving this.
Question 2
A turbulent flow scenario has u_max = 5 m/s at the centerline. If the parameter u* is calculated to be 0.5 m/s, and y is 0.1 m, determine the velocity at this y position.
💡 Hint: Ensure to convert the units to SI throughout the calculation.
