Challenge Problems
Push your limits with challenges.
Question 1
Consider a particle moving in a velocity field defined by u=x², v=2xy, and w=z. Calculate both local and convective accelerations at the point (1,2,1).
💡 Hint: Use differentiation rules to compute partial derivatives for both types of acceleration.
Question 2
A fluid flows over a surface at 2 m/s in the x-direction. If a particle within this fluid has a velocity variation of 0.5 m/s at a point, how do you quantify local and convective acceleration in this scenario?
💡 Hint: Consider how the particles' motions relate to their position in the velocity field.
