Challenge Problems
Push your limits with challenges.
Question 1
Given the pressure gradient in a two-dimensional flow system, derive an expression for the velocity field and determine how changes in the gradient might affect wall shear stress.
💡 Hint: Take careful note of your boundaries and pressure values.
Question 2
You have a fluid passing a flat plate where the Reynolds number is known. Discuss how altering this would transition through boundary layers.
💡 Hint: Review critical Reynolds numbers and flow classifications!
