Challenge Problems
Push your limits with advanced challenges
A water pipe with a diameter of 0.5 m and length of 200 m has a roughness of 0.02 m. The flow velocity is 3 m/s. Calculate the head loss using the Darcy-Weisbach equation assuming the friction factor has been determined to be 0.04.
💡 Hint: Apply the Darcy-Weisbach equation step by step for proper calculation.
Discuss how varying roughness in a pipe system changes the energy dissipated during flow and relate this to practical applications in urban water supply.
💡 Hint: Connect this concept with real-world implications for efficiently managing water resources.
