Question 1
A pipe with a diameter of 20 cm carries water at a speed of 5 m/s. Through some adjustments, the shear stress at the wall drops. Calculate the new speed if the shear stress doubles.
💡 Hint: Consider how changes in shear stress impact velocity.
Question 2
A surface shows a significant height of irregularities (k). If k = 0.2 mm and δ (viscous sublayer) = 0.5 mm, is it a smooth, transitional, or rough boundary? Calculate and explain.
💡 Hint: Refer to the definitions of boundary classification.
