An ideal fluid is___________________?
Correct answer: A. Frictionless & incompressible
- A. Frictionless & incompressible
- B. One, which obeys Newton's law of viscosity
- C. Highly viscous
- D. None of these
Explanation
An ideal fluid is modeled as having zero viscosity, so it is frictionless, and constant density, so it is incompressible. Newton’s law of viscosity describes Newtonian fluids, not ideal fluids specifically.
