Challenge Problems
Push your limits with challenges.
Question 1
A circular pipe has a diameter of 0.1 m and carries a fluid with viscosity 0.001 Pa·s. If the pressure drop over a length of 2 m is 50 Pa, calculate the flow rate using Poiseuille’s Law.
💡 Hint: Substitute appropriately for pressure, radius, and viscosity to find the flow rate.
Question 2
Describe the relationship between pipe length and required pressure drop for maintaining a steady flow. How does this relate to practical piping systems?
💡 Hint: Think about practical applications in engineering and how they correlate with pressure and length.
