Challenge Problems
Push your limits with challenges.
Question 1
If you have a flow rate of 3 m/s over a flat plate with a known displacement thickness of 0.02 m, how would you calculate the total mass flux reduction?
💡 Hint: Think about how mass flux is defined in terms of density and velocity.
Question 2
Given a specific viscosity, what would happen in a system if the boundary layer thickens significantly beyond typical assumptions?
💡 Hint: Review how flow regimes change based on the thickness of the boundary layer.
