Challenge Problems
Push your limits with challenges.
Question 1
A fluid has a velocity field represented as V = (2x, 3y, -y). Calculate the material accelerations at the point (1, 2, 1).
💡 Hint: Consider looking at spatial derivatives to derive acceleration components.
Question 2
Given a velocity function V(x,t) = 5x^2 + t and the density of fluid ρ(y) = 2y, find the material derivative of velocity.
💡 Hint: Use partial derivatives as you connect variables to their respective equations.
