ideal fluid vs real fluid-difference between ideal fluid and real fluid
This page compares ideal fluid vs real fluid and mentions difference between ideal fluid and real fluid.
• Definition: A fluid is said to be ideal if it is assumed to be both incompressible and non viscous.
• Its bulk modulus is infinite.
• ideal fluid has no surface tension.
• Ideal fluid is a substance which is unable to resist internal shear and tensile forces.
• Ideal fluid are imaginary and do no exist in nature.
• They have laminar (smooth)flow as shown in the figure.
• Definition: A fluid which is compressible, has viscosity and surface tension, is
known as real fluid.
• Real fluids implies friction effects.
• They have turbulent flow as shown in the figure.
• Examples: kerosene, petrol, castor oil
