Challenge Problems
Push your limits with advanced challenges
Given u = z + x² and v = -2y, derive the components of rotation about all axes.
💡 Hint: Make sure to apply the definitions accurately.
If a flow field is defined by u = 3x - 5y, v = 8y + z, determine under which conditions it is irrotational.
💡 Hint: Check the relationship between derivatives and irrotational flow.
