Which of the following must be followed by the flow of a fluid (real or ideal)? (I) Newton's law of viscosity. (II) Newton's second law of motion. (III) The continuity equation. (IV) Velocity of boundary layer must be zero relative to boundary. (V) Fluid cannot penetrate a boundary?
Correct answer: B. II, III, V
- A. I, II, III
- B. II, III, V
- C. I, II, V
- D. II, IV, V
Explanation
Newton's second law and continuity apply to fluid motion, while an impermeable boundary cannot be penetrated, giving the normal-velocity condition. Newton's law of viscosity and zero relative velocity are not required for an ideal fluid, so statements I and IV are excluded.
