Challenge Problems
Push your limits with advanced challenges
A cylindrical pipe has an inner diameter of 20 cm and carries water at a velocity of 5 m/s. Calculate the shear stress at the wall and identify whether the boundary is rough or smooth given the height of surface irregularities is 0.2 mm.
💡 Hint: Memory aids can assist in relating the mathematical aspects to physical properties of the flow.
A fluid with a viscosity of 0.002 Pa·s is flowing over a material with k = 0.3 mm. If delta dash is 0.1 mm, determine if the flow is turbulent and the nature of the boundary.
💡 Hint: Use the ratios discussed to identify boundary types.
