What does the "C factor" measure in pipe systems?

The "C factor" is a critical parameter when evaluating pipe systems, particularly in the context of hydraulics and fluid mechanics. It measures the roughness of the interior surface of the pipe, which plays a significant role in determining the flow characteristics of liquids moving through the system.

Roughness affects the resistance to flow; as the roughness increases, flow is impeded, leading to higher friction losses. This factor is essential for engineers and designers when calculating the hydraulic capacity of a pipe, as it directly influences how much fluid can be transported efficiently. Understanding the C factor is crucial for ensuring that systems are designed to minimize energy losses and to maintain adequate flow rates.

While flexibility, pressure ratings, and thickness are important characteristics of a pipe, they do not directly correlate with the C factor. Instead, they pertain to other mechanical properties that influence the durability and strength of the pipe material, not the flow dynamics resonating from the pipe’s internal surface texture.
