Challenge Problems
Push your limits with challenges.
Question 1
You have a pipe with a diameter of 0.1 m narrowing to 0.05 m. If the flow rate is 300 L/min, calculate the velocities at both points and determine if the flow is laminar or turbulent based on the Reynolds number.
💡 Hint: Convert L/min to cubic meters per second for calculations.
Question 2
A system has a globe valve causing a head loss of 5 m and a gate valve causing a head loss of 12 m for the same flow conditions. Analyze the implications of using these valves in system design.
💡 Hint: Consider how energy losses affect system efficiency over time.
