Challenge Problems
Push your limits with challenges.
Question 1
A pipe system experiences a transition from laminar to turbulent flow at a Reynolds number of 2500. How might the design of the system need to change to minimize energy losses?
💡 Hint: Consider the characteristics of laminar versus turbulent flow.
Question 2
Calculate the energy loss in a pipe fitting where the velocity of water is increased, causing vortex formation. Given the initial velocity as 2 m/s and the new velocity as 5 m/s, how do the energy losses compare?
💡 Hint: Use the principle of kinetic energy change!
