What is fluid :
A fluid is a substance which deforms continuously when it is subjected to external shearing forces.
Characteristics of Fluid :
A fluid is a substance which deforms continuously when it is subjected to external shearing forces.
Characteristics of Fluid :
- It has no proper shape of its own but conforms to the shape of the containing vessel.
- A fluid can be defined unambiguously as a material that deforms continuously and permanently under the application of shearing stress, no matter how small.
- The fluid has elastic properties only under direct compression.
1. Ideal Fluid
An ideal fluid is one which has
- No viscosity
- No surface tension
- Incompressible
2. Real Fluid
A Real fluid is one which has
- Viscosity
- Surface tension
- Compressible
Naturally available all fluids are real fluid.
