where \( Re \) is the Reynolds number. However, as the flow transitions to a turbulent regime, the calculation becomes more complex. The turbulent flow friction factor is determined using empirical correlations, such as the Colebrook-White equation, which accounts for both the Reynolds number and the relative roughness of the pipe.

When selecting the thickness of a galvanized iron sheet, it is essential to consider factors such as load-bearing requirements, environmental conditions, and the specific application. For instance, a thicker sheet is ideal for roofing and wall cladding in areas prone to heavy rain or wind, as it can better withstand harsh weather conditions. On the other hand, thinner sheets are suitable for applications like interior partitions or decorative elements where strength requirements are less critical.

A cap sheet is a waterproof material used in flat roofing systems, typically installed on the top layer of the roof to provide protection. It forms a barrier against weather elements, ensuring that water cannot penetrate through to the structure beneath. This is crucial as leaks can lead to devastating damage, including rot, mold, and structural weakness.
