Bernoulli's Law is applicable to which type of fluids?

Bernoulli's Law is specifically applicable to fluids that are in motion, as it describes the behavior of flowing fluids in terms of their velocity, pressure, and elevation. This principle states that for an incompressible, non-viscous fluid flowing along a streamline, an increase in the fluid's velocity results in a decrease in pressure or potential energy.

In the context of applying Bernoulli's Law, the focus is on how energy is conserved in moving fluids. The law is often utilized in various applications like aerodynamic lift, flow of liquids in pipes, and in explaining how airplanes achieve lift. The key aspect here is that Bernoulli’s principle is not relevant to fluids that are stationary or static, as it requires a moving fluid to demonstrate the relationship between velocity and pressure.
