WebDec 19, 2016 · Traditionally, most engineers used an “n” of 0.013 for sewer-pipe design. However, the advent of smooth-walled PVC sewer pipe in the 1960s with an “n” of 0.009 … WebRough wall, or corrugated pipe, have relatively high “n” values which are approximately 2.5 to 3 times those of smooth wall pipe. All smooth wall pipes, such as concrete and plastic, were found to have “n” values ranging between 0.009 and 0.010, but, historically, engineers familiar with sewers have used 0.012 and 0.013. This “design ... samsung tv with picture in picture
