Challenge Problems
Push your limits with challenges.
Question 1
Consider a fluid with a maximum velocity of 5 m/s. The distance between two plates is 0.2 m and the viscosity is 3.5 Pa·s. Calculate the average velocity and the pressure gradient.
💡 Hint: Make sure to apply the correct velocity relationship first.
Question 2
A fluid flows between two parallel plates, causing a shear stress of 80 N/m² at the wall. If the thickness of the plates is 0.15 m, calculate the pressure gradient.
💡 Hint: Identify the transition from shear stress to pressure gradient effectively.
