### HYDRAULICS FOR GRAVITY SEWER PIPE: A FEW THINGS TO

Many know that Polyvinyl Chloride (PVC) has a Manning’s n value of 0.009, but they conservatively use 0.012/0.013 based on Reinforced Concrete Pipe’s historical values after adjusting for s of the pipe wall and joints. Since PVC is highly resistant to s, this is considered as an overly conservative nuer, but we know it will work.
