Challenge Problems
Push your limits with challenges.
Question 1
Given a pipe with a diameter of 0.5 m, roughness of 0.05 mm, and a flow rate that results in a Reynolds number of 2,000,000, calculate the friction factor using both the Colebrook formula and the Haaland equation.
💡 Hint: Look up both equations for solving f.
Question 2
For a system using a pipe diameter of 0.25 m and an equivalent roughness of 0.21 mm at a flow velocity of 3 m/s, derive the Reynolds number first and then both friction factors.
💡 Hint: Make sure to verify your flow type first!
