Challenge Problems
Push your limits with challenges.
Question 1
A pipe has a diameter of 0.5 m and a roughness height of 0.01 m. Calculate the friction factor for turbulent flow using entries from Moody's diagram.
💡 Hint: Consider the flow implications at this scale.
Question 2
A square duct of side length 1 m has a flow of water with a Reynolds number of 5000. Determine whether the flow is laminar or turbulent and calculate the hydraulic diameter.
💡 Hint: Refer to the critical Reynolds number to classify flow type.
