In an era where sustainability is a priority, coil metal emerges as an eco-friendly roofing option. Many coil metals are made from recycled materials, reducing the demand for virgin resources. Additionally, metal roofing reflects sunlight, which can lead to lower energy costs by keeping buildings cooler. This energy efficiency is particularly valuable in warmer climates, where air conditioning can significantly drive up electricity bills. Moreover, at the end of its lifespan, coil metal roofing can be recycled again, minimizing its impact on landfills.

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.
