Challenge Problems
Push your limits with advanced challenges
A 1000 m length of 0.1 m diameter pipe has a friction factor of 0.02. What is the head loss if the flow velocity is 2 m/s?
💡 Hint: Check your units! They must be consistent throughout the equation.
You need a pump for a system with a total head of 50 m and minor losses adding up to 10 m. If the required flow rate is 0.1 m³/s, calculate the necessary horsepower.
💡 Hint: Check your pump design; consider efficiency losses.
