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.

An paramount feature that sets heated washable blankets apart is their washable nature. Historically, one of the major drawbacks of electric blankets was the difficulty in cleaning them. Fear of damaging the electrical components meant that many were resigned to being spot-cleaned. However, modern innovations have resolved this issue. Many heated blankets today are fully machine washable, with removable cords and controls that make maintenance a breeze. This ease of care ensures that the blanket remains hygienic and in top condition year after year.
