Bernoulli's principle states that the total energy of a hydraulic liquid is:

Bernoulli's principle is a fundamental concept in fluid dynamics that describes how the pressure of a moving fluid decreases as its velocity increases and vice versa. This principle emphasizes the conservation of energy in a flowing fluid, which can be understood in terms of three key types of energy: kinetic energy, potential energy, and fluid pressure.

The correct response highlights that the total energy of a hydraulic liquid, when following Bernoulli's principle, is the sum of kinetic energy and potential energy. Kinetic energy pertains to the energy that the fluid possesses due to its motion, which is influenced by the fluid's velocity. Potential energy is associated with the height of the fluid above a reference point in a gravitational field, affecting how gravitational forces impact the fluid's energy.

By stating that the total energy is the combination of these two forms of energy, the correct choice captures the essence of Bernoulli’s equation, which can be expressed as:

Total Energy = Kinetic Energy + Potential Energy + Fluid Pressure

This relationship shows that as one energy component changes, the other components must adjust to conserve the total energy of the system, illustrating the dynamic balance described by Bernoulli's principle.
