Challenge Problems
Push your limits with advanced challenges
A pipe system with a length of 1500 m and diameter of 0.10 m has a friction factor of 0.045. If the flow velocity is 3 m/s, calculate the head loss due exclusively to friction.
💡 Hint: Keep units consistent and pay attention to decimal placements.
Design a pump system for a pipe that connects two reservoirs 40 m apart in elevation with a required flow rate of 12 L/s. The pipe loses 5 m due to fittings and has a calculated head of 10 m due to friction. What horsepower is required?
💡 Hint: Break down the components of elevation, fittings, and friction carefully.
