Challenge Problems
Push your limits with challenges.
Question 1
Consider a fluid's velocity vector field given by v(x,y,z) = (2xy, x^2+y^2, z^2). Calculate the material derivative for a fluid particle moving along this path.
💡 Hint: Use the chain rule to find the changes in terms of time.
Question 2
Given a shear strain from a velocity distribution in a fluid, calculate the shear stress using the relationship between strain and stress under Newtonian fluid assumptions.
💡 Hint: Identify the proper gradient from the velocity field.
