Question 1
A flat plate is subjected to uniform flow. Calculate the shear stress at the laminar sub-layer when the dynamic viscosity is 0.001 Pa·s, and the velocity gradient is 10 s^-1.
💡 Hint: Apply the shear stress equation directly with the given values.
Question 2
In a hydraulic system, how does understanding boundary layer principles affect the design of a pipe? Discuss the consequences of neglecting them.
💡 Hint: Think about the practical applications and possible flow outcomes in real systems.
