TYPES of FLUIDS: Ideal fluid, Real fluid, Newtonian fluid, Non-Newtonian fluid, Ideal plastic fluid

TYPES of FLUIDS

The fluids may be classified in to the following five types.

1. Ideal fluid 

2. Real fluid 

3.Newtonian fluid 

4. Non-Newtonian fluid 

5. Ideal plastic fluid

1. Ideal fluid: 

A fluid which is compressible and is having no viscosity is known as ideal fluid. It is only an imaginary fluid as all fluids have some viscosity.

2. Real fluid: 

A fluid possessing a viscosity is known as real fluid. All fluids in actual practice are real fluids.

3. Newtonian fluid: 

A real fluid, in which the stress is directly proportional to the rate of shear strain, is known as Newtonian fluid.

4. Non-Newtonian fluid: 

A real fluid in which shear stress is not

Proportional to the rate of shear strain is known as Non- Newtonian fluid.

5. Ideal plastic fluid: 

A fluid, in which shear stress is more than the yield value and shear stress is proportional to the rate of shear strain is known as ideal plastic fluid.
