One of the primary determinants of the friction factor is the roughness of the inner surface of the pipe. Galvanized iron pipes often exhibit a relatively high level of roughness compared to other materials, such as PVC or copper. This rough surface can lead to increased turbulence in the fluid flow, resulting in a higher friction factor. Suppliers need to pay close attention to the manufacturing processes that can influence the surface finish of their pipes. Techniques such as improved galvanization methods or surface treatments could significantly reduce the internal roughness and thereby lower the friction factor.

Another notable feature of cast iron flat pans is their durability. When properly cared for, these pans can last a lifetime, or even longer. Unlike non-stick options that may wear out or scratch over time, cast iron is virtually indestructible. This longevity makes them a fantastic investment for any kitchen. Additionally, their ability to develop a natural non-stick surface through seasoning only enhances their usability over time.
