Challenge Problems
Push your limits with challenges.
Question 1
Consider a fluid flowing between two plates, both fixed, under a pressure gradient. If the pressure difference across the length of one meter is known, how would you calculate the flow rate?
💡 Hint: Remember to use the velocity distribution relevant to pressure-driven flow.
Question 2
Derive the shear stress acting on the plate when fluid flows due to a pressure gradient. What parameters do you need to consider?
💡 Hint: Focus on the definition of shear stress and how it relates to viscosity.
