Fluid Energy:

In a system where gravity is not involved, the total fluid energy is equal to the potential energy (pressure) component, plus the kinetic energy (velocity) component.

In a simple example, velocity is moderate in the tube of large diameter, while the transmural pressure is great (indicated by arrow length). Velocity must increase when the fluid passes into the smaller tube, necessitating a decrease in the pressure component. It is assumed there is no friction in this simple system.
