The fluid in which the shearing stress within it is proportional to the velocity gradient across the sheared section, is called a _____________ fluid?
Correct answer: A. Newtonian
- A. Newtonian
- B. Bingham
- C. Perfect
- D. None of these
Explanation
Newtonian fluids obey Newton's law of viscosity, τ = μ(du/dy), so shear stress is directly proportional to the velocity gradient. Bingham fluids require a yield stress before they begin to flow.
