The velocity field in a fluid is given to be V = (4xy)î + 2(x² - y²)ĵ. Which of the following statement(s) is/are correct?

  1. The velocity field is one-dimensional.
  2. The flow is incompressible.
  3. The flow is irrotational.
  4. The acceleration experienced by a fluid particle is zero at (x = 0, y = 0).

Correct answer: The flow is incompressible.

Solution

The flow is incompressible because the divergence of the velocity field is zero, indicating that the fluid density remains constant throughout the flow.
