The correct statement about ideal fluid is:a)An ideal fluid is incompr...
A fluid is said to be ideal if it assumed to be both incompressible and non-viscous, its bulk modulus is infinite. An ideal fluid is a fluid that has several properties including the fact that it is:
Incompressible - the density is constant
Non-viscous - (Inviscid) fluid has no internal friction.

The correct statement about ideal fluid is:
An ideal fluid is incompressible, non-viscous, and has an infinite bulk modulus.
Explanation:
An ideal fluid is a theoretical concept used in fluid mechanics to simplify the analysis of fluid flow. It is defined by certain characteristics that differentiate it from real fluids.
Incompressibility:
- An ideal fluid is considered to be incompressible, which means its density remains constant regardless of the pressure applied.
- In practical terms, this implies that the volume of an ideal fluid does not change even when subjected to high pressures.
- This assumption is often valid for liquids like water or oil, but not for gases.
Non-viscous nature:
- An ideal fluid is assumed to be non-viscous, meaning it has zero viscosity.
- Viscosity is the property of a fluid that causes it to resist flow and create internal friction.
- In an ideal fluid, there is no internal friction between fluid layers, and the fluid flows without any resistance.
Infinite bulk modulus:
- The bulk modulus is a property that measures the compressibility or resistance to compression of a fluid.
- An ideal fluid is considered to have an infinite bulk modulus, which means it is completely resistant to compression.
- In practical terms, this implies that an ideal fluid cannot be compressed or its volume cannot be changed by applying external pressure.
- This assumption is valid for incompressible fluids like liquids, where the change in volume due to pressure is negligible.
Conclusion:
The correct statement about an ideal fluid is that it is incompressible, non-viscous, and has an infinite bulk modulus. These assumptions help simplify fluid flow analysis and are applicable to certain fluids like liquids. However, it is important to note that real fluids do not completely fulfill these ideal characteristics.
