Q: What is an ideal fluid?
  • A. Very viscous
  • B. One which obeys Newton law of viscosity
  • C. Compressible flow
  • D. Frictionless and incompressible
Correct Answer: Option D - An ideal fluid (perfect fluid) is a non-viscous, frictionless and incompressible. The ideal liquid has no surface tension and the bulk modulus is infinite. An ideal fluid really does not exist.
