, 1.An ideal fluid is a theoretical concept used in fluid mechanics to simplify the analysis of fluid flow.
An ideal fluid is characterized by the following properties and behaviors:
Incompressibility: An ideal fluid is incompressible, meaning its density remains constant
regardless of changes in pressure. There is no variation in volume even when subjected to
different forces or pressures.
No Viscosity: An ideal fluid has zero viscosity, meaning there is no internal friction between
fluid layers as they move past each other. In real fluids, viscosity causes resistance to flow, but
in an ideal fluid, the flow is frictionless.
Steady Flow: The flow of an ideal fluid is steady, meaning that the fluid's velocity at any given
point does not change over time.
Irrotational Flow: Ideal fluid flow is irrotational, meaning there are no "vortices" or rotations
within the fluid elements. Each fluid element moves in a straight path without spinning.
No Heat Conduction: An ideal fluid does not exchange heat with its surroundings, and thermal
energy is not considered in its behavior.
No Surface Tension: There are no surface forces acting within an ideal fluid, meaning no
phenomena like surface tension exist.
