Challenge Problems
Push your limits with advanced challenges
Calculate the head loss over a pipe of 1000m length with a diameter of 2m, given a friction factor of 0.02 and a flow rate of 5m³/s. Discuss how factors would change if the pipe material changed.
💡 Hint: Plug in the values properly into the formula.
Compare the result of head loss using the Darcy-Weisbach formula for two different pipe materials, explaining how their roughness affects power efficiency over a given length.
💡 Hint: Review roughness parameters before calculation.
