Challenge Problems
Push your limits with challenges.
Question 1
Design a pipe system where you want to ensure fully developed laminar flow. Discuss dimensions and flow rates based on given material characteristics.
💡 Hint: Use laminar flow formulas to ensure your design meets criteria.
Question 2
Consider a scenario where a fluid is flowing in a long horizontal pipe of constant diameter. If the fluid changes temperature, affecting viscosity, how would this impact pressure drop and shear stress?
💡 Hint: Link viscosity changes to friction and pressure equations.
