The principle that states that total fluid energy along a streamline of fluid flow is constant is Bernoulli's Principle. This principle is fundamental in fluid dynamics and describes the relationship between the velocity of a fluid and its pressure within an ideal fluid, which is incompressible and non-viscous.

Bernoulli’s Principle asserts that as the speed of a fluid increases, the pressure within that fluid decreases, and vice versa. This principle can be observed in various applications, such as in the lift generated by airplane wings and the design of Venturi meters. When fluid flows smoothly along a streamline, the sum of the kinetic energy, potential energy (due to elevation), and pressure energy remains constant, allowing for predictions about fluid behavior in different scenarios.

Other principles mentioned do not relate directly to the constancy of fluid energy along a streamline. Pascal's Principle pertains to the transmission of pressure in fluids; Archimedes' Principle deals with buoyancy and the upward force exerted on objects submerged in fluids; and Newton's Law primarily addresses the motion of objects and force rather than fluid dynamics. Each of these principles has its own significance but does not encompass the complete energy dynamics described by Bernoulli's Principle.
