kS = The roughness of the pipe wall* (m) * Since the energy dissipation is associated with shear stress at the pipe wall, the nature of the wall surface will be influential, as a smooth surface will interact with the fluid in a different way than a rough surface. All these variables ...
LSAW 219 - 3120mm 3 - 25mm SEAMLESS 1/4 - 36 inch 1.25 - 50mm API 5L Grade B Carbon Steel Pipe Roughness Roughness of API 5L Grade B is not defined, new commercial pipe is approx 0.0018 in x 25.4 = 0.04572 mm. As per the engineers there is no guarantee it will be better, or...
The block approximates this value by using the empirical Haaland equation and the Internal surface absolute roughness parameter. The block takes the differential over each half of the pipe segment, between port A to an internal node, and between the internal node and port B. Pressure ...

On the other hand, seamless pipes are more expensive than ERW pipes, they are likely to have non-uniform thickness around their cross-section and they usually have significant roughness on their inside and outside surfaces. View chapter Book 2023, Structural Mechanics and Design of Metal Pipes...
Its roughness causes friction between the sides of the pipe and the water, decreasing the water speed. Also, in the coefficient of discharge calculator, we described the metric related to the theoretical and actual flow rates. Be sure to check it out if you're interested! Hazen-Williams ...
