Challenge Problems
Push your limits with advanced challenges
A fluid with a dynamically variable viscosity flows through a pipe with a diameter of 0.1 m. If the wall shear stress is measured to be 50 Pa, calculate the required flow rate if the flow remains laminar.
💡 Hint: Use the relationship of shear stress in laminar flow.
Explain how you would use stream functions to model the flow around a ship hull. Include the variables you would consider.
💡 Hint: Think of hydrodynamics and how they relate to vessel design.
