Challenge Problems
Push your limits with advanced challenges
A water pipe sudden enlarges from 4 cm to 8 cm in diameter, experiencing a pressure change of 1 atm. How would you calculate the flow rate at each section? Consider applying the Bernoulli equation.
💡 Hint: Remember that when the diameter increases, the velocity must decrease under conservation laws!
Calculate the kinetic energy correction factor for a channel flow that has a parabolic velocity profile. Assume the velocity at the center is twice that of the average velocity.
💡 Hint: Visualize the flow profile and how average velocity differs from local velocities.
