's First Law of Motion: The fluid will continue to flow in a straight line at a constant velocity unless acted upon by an external force.

b) Conservation of Mass: The mass of the fluid entering a particular region must be equal to the mass of the fluid leaving that region. In other words, mass cannot be created or destroyed within the flow.

c) Conservation of Energy: The total energy of the fluid must remain constant along its flow path. This includes potential energy, kinetic energy, and any other form of energy associated with the fluid.

d) Continuity Equation: The rate of flow of the fluid must be constant at any given point along the flow path. This is expressed mathematically as the product of the cross-sectional area and the velocity of the fluid remaining constant.

e) Bernoulli's Principle: The pressure exerted by a fluid decreases as its velocity increases, and vice versa, as long as the fluid is in a steady flow without any external forces acting on it.

f) Conservation of Momentum: The total momentum of the fluid must remain constant along its flow path. This means that any change in the fluid's velocity or direction must be offset by an equal and opposite change in momentum.

g) Laminar Flow: Ideally, the fluid should flow smoothly in parallel layers without any turbulence or mixing. This ensures efficient and predictable flow behavior.

h) No-Slip Condition: The fluid in contact with solid surfaces should adhere to those surfaces and have zero velocity relative to them. This ensures that there is no relative motion between the fluid and the solid surface.

Overall, an ideal flow of any fluid should exhibit smooth, steady, and predictable behavior while conserving mass, energy, and momentum throughout its flow path.
