Pipe Diameter vs. Pressure vs. Flow for Piping Systems

When examining pipe flow, the focus is often on the pressure difference between two distinct points along the pipe, instead of the absolute pressure inside the pipe. Flow describes the movement of fluid within the pipe.

Flow vs. Pressure

The relationship between flow and pressure is described by Bernoulli's principle, which states that an increase in fluid velocity leads to a decrease in pressure, and vice versa, assuming no energy losses or external forces acting on the fluid.
