Question 1
What is the no-slip boundary condition?
- The fluid velocity at a boundary is zero.
- Fluid velocity increases steadily at the boundary.
- Fluid velocity is constant across all areas.
💡 Hint: Consider what happens to fluid at a solid boundary.
Question 2
True or False: Shear stress is always constant in the boundary layer.
- True
- False
💡 Hint: Think about how shear stress relates to fluid dynamics.

Challenge Problems
Push your limits with challenges.
Question 1
If a fluid with a viscosity of 0.002 Pa.s experiences a velocity gradient of 200 s^-1 at a boundary, calculate the shear stress at that boundary.
💡 Hint: Apply the shear stress formula.
Question 2
Discuss the impact of a thicker boundary layer on fluid flow and sediment transport in rivers.
💡 Hint: Consider how reduced shear stress affects movement.
