Challenge Problems
Push your limits with challenges.
Question 1
Design a piping system that transports water across a distance of 200 meters with a target head loss of less than 5 meters. What diameter and flow velocity would you select? Assume a Darcy friction factor of 0.04.
💡 Hint: Start with rearranging the equation to solve for diameter or velocity.
Question 2
A pipe with a diameter of 0.15 m and length of 100 m is transporting water with a velocity of 4 m/s. What happens if you increase the diameter to 0.2 m? Calculate the new head loss based on the Darcy friction factor of 0.025.
💡 Hint: Calculate both head losses and compare results.
