Challenge Problems
Push your limits with challenges.
Question 1
For a control volume in a turbulent flow where pressure varies across the surface, derive the expression of the resultant force balance accounting for gauge pressure.
💡 Hint: Use known relationships between force, pressure, and area during integration.
Question 2
Given a scenario in a structural beam under fluid flow, analyze the stress distribution using the stress tensor and suggest modifications to reduce shear stress effects.
💡 Hint: Consider geometric shapes that minimize shear forces.
