Challenge Problems
Push your limits with advanced challenges
A water pipe with a diameter of 0.1m and length of 50m has a roughness height of 0.005m. If the velocity of water is 1.5 m/s, calculate the friction factor and the head loss using the Darcy-Weisbach equation.
💡 Hint: You need to check if the flow is laminar or turbulent first!
Design a piping system to limit head loss to 5m for a flow of 75 liters per minute over a 100m length pipe. If the roughness is 0.01m, calculate the appropriate diameter of the pipe.
💡 Hint: Use Q = A * V to relate the diameter to the flow.
