Challenge Problems
Push your limits with challenges.
Question 1
A fluid flows through a tapered pipe. At the wider section, the diameter is 0.5 m and the velocity is 4 m/s. Calculate the velocity at a narrower section with a diameter of 0.2 m.
💡 Hint: Remember to calculate the areas first!
Question 2
Explain how the local and convective acceleration act on a fluid particle moving through a bend in a pipe.
💡 Hint: Think about how the particle experiences a change in velocity when entering a bend.
