Correct Answer - Option 4 : A - 4, B - 3, C - 1, D - 2

Explanation:

Ideal fluid:

  • Ideal fluid is Incompressible and it has zero value of shear force.
  • The ideal fluid does not actually exist in nature, but sometimes used for fluid flow problems.
  • An ideal fluid is a fluid that has several properties including the fact that it is :
    • Incompressible – the density is constant
    • Irrotational – the flow is smooth, no turbulence
    • Nonviscous – (Inviscid) fluid has no internal friction

Newtonian fluids:

  • Newtonian fluids defined as fluids for which the shear stress is linearly proportional to the shear strain rate
  • Newtonian fluids are analogous to elastic solids (Hooke’s law: stress proportional to strain)
  • Any common fluids, such as air and other gases, water, kerosene, gasoline, and other oil-based liquids, are Newtonian fluids
  • \(\tau = \mu \frac{{du}}{{dy}}\) where μ is shear viscosity of the fluid

Non-Newtonian fluids​

  • Fluids for which the shear stress is not linearly related to the shear strain rate are called Non-Newtonian fluids examples include slurries and colloidal suspensions, polymer solutions, blood, paste, and cake batter.

Real Fluid

  • All the fluids are real as all the fluids possess viscosity.
