WebMaterial Manning's n; PIPES: Reinforced concrete: 0.013: Vitrified clay pipe: 0.013: Corrugated metal pipe: 0.023: Polyvinyl chloride (PVC) 0.010: Smooth welded pipe WebThe friction factor or Moody chart is the plot of the relative roughness (e/D) of a pipe against the Reynold's number. The blue lines plot the friction factor for flow in the wholly turbulent region of the chart, while the straight black line plots the friction factor for flow in the wholly laminar region of the chart. In 1944, LF Moody plotted ...
WebAbsolute roughness for PVC (ε) = 0.0015 mm. Pipe nominal diameter (D) = 3" = 76.2 mm. Relative roughness of 3" PVC pipe = ε/D = 0.0015 / 76.12 = 1.97 × 10 -5. Next this relative … Webbecause of friction at the pipe wall. For turbulent flow of fluids in circular pipes, there is a layer of laminar flow called the laminar sublayer adjacent to the pipe wall. If this laminar sublayer is thicker than the roughness of the pipe wall, then flow is “hydraulically smooth” and the pipe has attained the ultimate in hydraulic efficiency.
