Question 1
Given a rough pipe with a diameter of 0.2 m and flow velocity at two distances 0.02 m and 0.04 m from the wall, calculate the roughness coefficient using provided velocity ratios.
💡 Hint: Start with the relationship between the two different velocities and apply the roughness correlation.
Question 2
How would a sudden increase in pipe roughness impact the velocity distribution in turbulent flow? Provide a detailed explanation.
💡 Hint: Analyze how turbulent flow transitions with changed coefficients and relate to derived equations.
