Challenge Problems
Push your limits with advanced challenges
A fluid flows through a pipe with a sudden diameter reduction. Calculate the expected increase in velocity and energy loss using Bernoulli’s principle and illustrate with a sketch.
💡 Hint: Remember to take into account the initial and final pressures.
If a system incorporates both a globe valve and a gate valve, how would you calculate the total energy losses and flow rates? Provide a comprehensive analysis.
💡 Hint: Use the K values associated with each valve type for accurate calculations.
