More about ideal .

Ideal fluids are a theoretical concept used to simplify fluid dynamics problems. They possess two key characteristics:

1. Incompressibility: The density of an ideal fluid does not change with pressure. This means that volume remains constant regardless of applied pressure.
2. Non-viscosity: Ideal fluids have zero viscosity, meaning there is no internal friction between fluid layers. This implies that no energy is lost due to friction as the fluid flows.

Because real fluids always have some viscosity and are not perfectly incompressible, ideal fluids represent an approximation that makes calculations more manageable, especially in introductory physics.
